爱德华·索普接受Barrons杂志采访时还回答了其他关于年老力衰的问题：

问：为什么现在持有$伯克希尔-哈撒韦B(BRK.B)$ 而不自己去寻找更好的机会？
答：当我35岁的时候，我有很多时间但是没那么多钱，所以在几乎没有风险的情况下每年多赚10个点是很吸引人而且有乐趣的。现在我85岁了，时间的边际价值更高，而钱的边际价值更低。如果我什么都不用做就能靠买BRK获得10%回报的话，我有很强的动机不去找其他投资标的了。
问：你现在85岁了，但是看上去还是像60多岁一样。你的秘诀是什么？

答：我能很清晰和理智的思考如何减缓衰老。我从20多岁开始就锻炼身体。47岁时我开始跑马拉松，现在已经跑了22次，最佳纪录是3.17小时。我每周花5小时做快走或慢跑。我请了一个教练一周健身两次。我觉得我应该做更多。我现在的BMI是22，我觉得这个可以了。我在饮食上希望聪明一点。我从来不抽烟，抽烟是最愚蠢的事情之一。我从来都没见过西蒙斯，最伟大的对冲基金经理，因为他是个老烟枪，我不愿意到他办公室去。我们应该思考自己的健康和健身计划，我们是自己最好的健康管理人。从现在开始管理健康，做一些总比什么都不错好，做多一些比少做一些好。


Q: Why not go out and find better investments, as you did in the past?


A: When I was 35, I had lots of time and less money, so doing 10% or so better than the index, with little risk, was attractive and fun. At 85, the marginal value of time is higher and the marginal value of money is lower. These are strong disincentives when I can make a long-run 10% or so by doing nothing.
Q: You’re 85 and look like you’re in your early 60s. What’s your secret?
A: I think rationally and clearly about how to slow aging. I’ve been exercising since my 20s. I started running marathons when I was 47. I’ve run 22; my personal lifetime best is 3.17 hours. I spend five hours a week in vigorous walking or easy jogging. I work out with a trainer twice a week. I feel I should do more. I have a body-mass index of 22 and am comfortable there. I try to eat semi-intelligently.
I have never smoked. It has got to be one of the stupidest things. I have never met Jim Simons of Renaissance, the greatest quant hedge fund guy ever, because he was a chain smoker and I didn’t want to go into his office. You should think about your overall health and fitness plan. You are your own best health manager. Get started by telling yourself: Some is better than none, and more is better than less.
