 The first time I met you, I was fascinated by the fact that you're talking so fluently about science and you love science, right? I love science, I love mathematics and I think what's happened in our world today in research, the lifespan of people is going to be extended and they're going to be able to do more things. And they're actively seeking better ways of treating people, not always after they get the illness, but before to prevent illness. Yeah, now you're so right. Everybody in the room today, we had like 200 people from around the country, best institution, they're all on the top of their career. I can tell you something, we all have in common. We all want to be like you. My main worry for me is not to stop walking, not to stop skiing and biking. My main worry is to have my brain and to be able to think. And this is the most important thing and you're so clear on this. Well my goal is every day to learn something new, something different. I would like to see your stem cells and I would like to do a study to compare them with people in the same age group as you because there is something very, very, very phenomenal here. Every day is a good day and every day is a learning day.
