絕種原生香米 冰存38年復生
2011-08-27 中國時報 【沈揮勝/南投報導】
▲瑞岩香米外觀呈現金褐色,與一般白米相較,體積大了約一倍半。(沈揮勝攝)
泰雅族醫師楊茂銀,卅八年前用家鄉瑞岩部落的原生香米蒸飯,招待來訪的恩師鍾文政,順手抓把穀子給老師留作紀念。這種形狀奇特的大型稻作,因稻熱病而全面絕滅,當年的「紀念品」去年物歸原主。楊茂銀細心育苗存活一芽,今年結穗纍纍成了保脈種源。
去年九月獲選「醫療終身奉獻獎」的楊茂銀,六十二年就讀北醫大時,恩師鍾文政為研究原住民罹患寄生蟲情形,花三天時間從梨山環山部落,徒步翻山越嶺抵南投縣仁愛鄉瑞岩部落。
楊茂銀拿收成的原生稻穀舂米招待,並順手抓一把穀子給老師。鍾文政將那把穀子帶回台北,以舊報紙封存,擺冰箱冷藏;卅多年來冰箱迭有更換,但這包「紀念品」始終未丟棄。
楊茂銀說,瑞岩原生稻六十二、三年還有人試著再插秧,但隨著化肥及改良種水稻被引進山區,原生稻或感染稻熱病、或穗而不稔,完全絕種。
原先在山地衛生所系統服務的楊茂銀,七十八年轉往信義鄉新中橫公路旁開業。九十八年底,鍾文政到信義鄉,找前鄉長全文章醫師及楊茂銀聚會敘舊。
席間,楊向鍾提及老師那一年吃的香米已經絕種。鍾文政回應:「我就知道總有一天,你會問我這件事。那一把穀,已擺在我冰箱卅七年!」
鍾文政承諾,北返後盡速郵寄那包稻穀。去年元月,楊茂銀抖著雙手,將裝有四、五百粒穀子的郵包分裝一半,委請中國醫藥大學教授吳金濱幫忙育苗。
吳金濱以培養皿育出一芽,楊茂銀則以傳統催芽方式育出三芽,但因操之過急誤加營養劑,只剩一芽存活。該芽從根部陸續竄出側芽,共結出十三束稻穗;收割後萌出的再生稻又抽出十多穗,兩期共收穫八千粒穀子。
今年春季,楊茂銀在診所側方一塊約六坪大的空地上,以去年的穀子分別播撒在數十只的盆盤中。他的太太高阿珠,擔心仁愛鄉的稻種,無法適應信義鄉的土質,還返瑞岩老家用車載回故鄉泥土栽植。
七月植株成熟,莖葉最高者達一八三公分,最矮者亦超過一三五公分,遠比一般稻米高出一倍,產量讓人驚訝。楊茂銀拉著老婆的手說:「謝謝妳的支持,謝謝幫忙運土,這漂亮的紫金色穀子,就用咱倆姓名末字來命名,稱它『銀珠香米』。」
銀珠香米七月底收割,穫量八公斤,刻正準備量產,再播四分地。農試所稻作研究室專家聞風趕來探究竟,直呼:「大開眼界,一輩子最驚奇的回憶!國家種源庫現有約八千種樣本,找不到如此特殊的原始種香糯米。」

子曰
Woman asks: If I sleep with 3 men, everyone calls me a slut.
But when a man sleeps with 8 girls, everyone calls him a real man. How come?
Confucius say: 'It's very simple.
When one lock can be opened by 3 different keys, it's a bad lock.
But when one key can open 8 different locks, we call it a master key'.

Retirement Plans for 1,000-Year-Olds
by Joe Mont
Wednesday, August 3, 2011
Medical strides have allowed people all over the world to live longer. According to one researcher, we are on the cusp of routinely living to 150, and the first person to blow out 1,000 candles on their birthday cake could be born within the next two decades.
Biomedical gerontologist Dr. Aubrey de Grey, of the California-based Strategies for Engineered Negligible Senescence Foundation, made those claims in a recent research paper. His prediction is that the increasing ability of scientists to engineer replacement tissue will allow for customizable, replaceable organs in the not-so-distant future.
Living to 150 or even 1,000 may not be as far-fetched as it might seem. In the U.S., life expectancy has nearly doubled since 1900. More telling, the number of 100-year-olds in 1990 totaled roughly 37,000, but there are more than 84,000 now and, according to Census Bureau projections, by 2050 there could be more than 580,000 Americans older than 100.
If mega aging occurs as de Grey theorizes, it would have a monumental impact on society. Would natural resources be able to keep pace with the population? How would governments and global economies manage?
As humans reach 150 years old and beyond, financial playbooks would be thrown out the window.
With "aging workforce" taking on a whole new meaning, employee churn would be rare. As companies hold onto employees for many decades, how will a younger workforce earn their paycheck?
A big question would be how long a person could continue to work and how long a post-career retirement would last. Would dementia and other physical ailments add millions to the ranks of the disabled, requiring ever-escalating financial and medical support for decade after decade?
The insurance industry would be thrown into chaos, as actuarial tables and mortality credits prove no longer viable in an era of artificially prolonged life. An upside for the industry might come from all those added years of premiums they can collect before a life insurance policy is paid out.
Retirement strategies would need to radically evolve to keep up with changes in society.
"Retirement is expensive and will become even more expensive in the future," said Jean-Claude Menard, chief actuary of the Office of the Superintendent of Financial Institutions in Canada, at the Society of Actuaries' symposium Living to 100 in January. "No matter if it is a fully funded plan or a pay-as-you-go plan, no matter if it is a [defined-benefit] or a defined-contribution solution, no matter if it is a national public scheme or a private pension plan, the fact is that increased longevity will continue to put pressure on the financing of pension plans."
Corporate pensions and government entitlement programs — Social Security and Medicare — would likely be stressed beyond their capability.
On top of the strain already felt in budgets for Social Security and Medicare, research shows that their funding gaps will increase along with the average age of beneficiaries.
A study by the MacArthur Research Network on an Aging Society found that by 2050 Americans may live 3.1 to 7.9 years longer than official government projections, resulting in sharply higher costs for government programs that serve older citizens. The study estimates that cumulative outlays for Medicare and Social Security could rise by $3.2 trillion to $8.3 trillion from current government projections by 2050.
"Even small changes in life expectancy produce large changes in the number of older Americans," said Dr. S. Jay Olshansky, a professor at the University of Illinois at Chicago's School of Public Health and one of the authors of the study. "Therefore, our projections of longer life expectancy have profound implications for America's fiscal situation, health care system and labor markets."
"Although the nation will become increasingly gray in subsequent decades, the United States is not well prepared to deal with the myriad consequences of this impending reality," said Dr. John Rowe, who chairs the MacArthur Research Network and is former CEO of Aetna.
With the ability to age like Methuselah, a massively longer time horizon for retirement savings might ease some of the concerns for investors.
If a preretiree were to add just an additional $1,000 a year to an initial 10,000 in a 401(k) or IRA (assuming a 5% compounding return), they will amass roughly $4 million over the course of a century. Saving or investing for 150 years would see that total rise to $6.7 million within 150 years and $536 million after 200 years.
The longer they live, the better the news: That mere $1,000 a year would accrue $6.1 billion over 250 years. By the time they reach 800 to 1,000 years old, they will hypothetically have trillions at their disposal.
Those science fiction-level returns may be of little consolation to a society on the cusp of making 100 years old the new norm.
A recent study by SunAmerica Financial Group and Age Wave, a research and consulting firm focused on population aging, found that 67% of respondents say they would like to live to 100. Among the advantages of living to 100 they cited were "remaining productive, establishing deep relationships with family, witnessing new discoveries and experiencing many years of leisure."
Jana Greer, president and CEO of SunAmerica Retirement Markets and senior vice president of SunAmerica Inc., says many Americans are postponing retirement because they have the health and willingness to work later into life. While 10 years ago most were planning to retire at about age 64 or 65, today's workers have moved that target up to 69. She refers to the trend as "Retirement 3.0."
"You might think they are delaying it simply because of the challenges obviously of the recession and the impact that has had on their financial condition," Greer says. "Actually, we are finding that people want to stay engaged. Not only are they working full-time longer, but one of the huge findings out of the study was that retirement doesn't mean 'retirement' any more. It doesn't mean the end of work. About two-thirds of the people in the study — both preretirees and retirees — want to stay working in some way during their retirement, whether it is part-time or flexible, coming in and out of the workforce."
Living longer, however, doesn't always mean being able to work longer or preserving savings.
Asked about the "major worries of living to 100," 73% of those surveyed cited serious health problems; 59% feared being a burden to their family; 49% said a top concern was running out of money; and 26% said they fretted about not being able to leave an inheritance for their family.
Those fears are reflected in investment goals. Priorities were to "not lose value" and "to protect their income stream from market loss and guarantee it for life," Greer says.
"I think people are realizing that with increased longevity they have got to plan for their future income stream, not just a lump sum that is going to tide them through," she adds.
These findings feed into SunAmerica's projection that the annuity marketplace, specifically the variable annuities they offer, will continue to grow in popularity among investors.
Research earlier this year by the Society of Actuaries revea led that as ages draw close to triple digits, many are woefully underprepared for the challenge.
Nearly half (48%) of the polled respondents, ages 45-70, "have no financial plans in place to protect themselves against outliving their assets and the rising cost of health care should they live longer than they expected," the research showed. More than one-third are worried about running out of money during retirement, but only 20%plan to buy an annuity or other form of guaranteed lifetime income to protect their assets.
The survey also found that 75% of those ages 45-70 protect their tangible assets, such as housing, through home or renter's insurance. Only 19%, however, plan to insure the extra costs of disability and well-being by buying long-term care insurance.
