Well, it is of course a step-by-step process that started back in the 80s. I was struggling to retrieve a little bit of DNA from things that were just a few … starting with just dried tissues that, you know, that were just a few months old, going back in time and struggling with the technological issues with that over a decade. And then it became possible to retrieve DNA from things like the mammoths or cave bears that lived at a similar time as the Neanderthals. And then I was very lucky to get a job in Germany, where of course Neanderthals is a big presence in our, in the imagination of people, so it was then very, an obvious next step, in a way, to try to do that.

No, because I started working on ribosomes when I was a post doc, in 1978, when it would have been impossible, really, to solve it. But, it was just a fundamental problem in biology. And we felt, no matter, anything we do to chip away at the problem would be useful. So it was more that that attracted me. And I think the fact that it was large and kind of difficult to come to grips with, yes, it was attractive. Really what was attractive was that it was a fundamental problem.

Her story is why I dedicate the Nobel Peace Prize money to the Malala Fund, to help give girls quality education, everywhere, anywhere in the world and to raise their voices. The first place this funding will go to is where my heart is, to build schools in Pakistan—especially in my home of Swat and Shangla.

And so I ran. I ran up and down every court After every loose ball for you. You asked for my hustle I gave you my heart Because it came with so much more.

The strategy we've adopted precludes our following standard diversification dogma. Many pundits would therefore say the strategy must be riskier than that employed by more conventional investors. We disagree. We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it.

Ironically, though, this is also the purchase in which I made my biggest mistake - of a kind, however, never recognized on financial statements. We paid $600 million in 1989 for Gillette preferred shares that were convertible into 48 million (split-adjusted) common shares. Taking an alternative route with the $600 million, I probably could have purchased 60 million shares of common from the company. The market on the common was then about $10.50, and given that this would have been a huge private placement carrying important restrictions, I probably could have bought the stock at a discount of at least 5%. I can't be sure about this, but it's likely that Gillette's management would have been just as happy to have Berkshire opt for common. But I was far too clever to do that.

Some material things make my life more enjoyable; many, however, would not. I like having an expensive private plane, but owning a half-dozen homes would be a burden. Too often, a vast collection of possessions ends up possessing its owner.

Well, I ran out of gas. You know, I got to be what, 93 at that time, or something like that. And it just – same reason I gave up teaching. I teach – I was – I taught every year from when I was 21 till 88 or 89, and there just came a period when your body said different things to you, and you should turn it over to somebody, just like I did at Berkshire.

Yeah and we get calls all the time, and there's so many calls, but the like I said, it takes me five seconds to say no. It takes, Greg's a little more polite than I am, but I just as soon get the calls just to see what people are doing. But they aren't offering anything that's at an attractive price, and what they want is a trade.

The number one rule I give them is just not give them the golden rule. Do unto others, I'm not a religious guy, but, I mean, nobody said it any better in a couple thousand years than that, which may be why it's lasted to a certain degree too. I mean, more people are reading a 2000-year-old book about how to behave than anything that anybody's coming up with lately. Now it's got a lot of, particularly the Old Testament, it's got different kinds of stories, to some extent, but if the whole world lived by the golden rule, it would be such a more wonderful society.
