Thank you very much, Madam Chair.
Thanks to the witnesses for being here today.
It's quite an interesting topic when you think that over the years, and as we progress further into...as years come by, we're going to live longer whether we want to or not, because technology is going to allow us to live longer.
Having said that, what do you foresee, let's say in 30 or 40 years, when the average human lives to 90, on average, and the average physician, who may still be working at 75, says, boy, what's the one thing we can do now to make people live longer?
