And what if you're found to have a 1.75 millimeter aneurysm, if it's really even an aneurysm, should you change your lifestyle?

And for something like that, I would recommend, no, you should forget about it.

get a follow-up scan, but you may very well live and die with this little blister that is of no consequence.

So as I say, I think you have to be careful about how you interpret and how you act on these things.

Well, I think it has to be individualized to some extent.

And over time, the standards and the guidelines have changed.

It used to be if your systolic blood pressure, that's the upper number, was under 130, 130 or under, that was considered normal and would not lead to problems.

Now, the guidelines suggest that 120 or lower is better in large studies.

But as an example, when my blood pressure gets under 120, I feel lightheaded.

In fact, I had an event about 15 years ago when I was overdoing it like I shouldn't have been.

Overdoing exercise or overdoing work?

Overdoing everything.

I was in my... A Stanford faculty member that overdoes something?

I was 56 years old.

And I operated all day in two operating rooms.

I got done early.

It was in the spring.

And I took a run up to the dish.

And then I took a red eye to Houston for a meeting.

And I emailed on the flight, got an hour or two of sleep, went to the meeting, was fine.
