"The other cutoff, 38, has a lot more play in it. One reason I put it there is that I don't think many people have the physical stamina much past that age. I used to work till 2:00 or 3:00 AM every night, seven days a week. I don't know if I could do that now.

Also, startups are a big risk financially. If you try something that blows up and leaves you broke at 26, big deal; a lot of 26 year olds are broke. By 38 you can't take so many risks-- especially if you have kids."

I don't see any bragging there. Those seem like reasonable and non-discriminatory observations.

I'm pretty happy that at 33 my life isn't really any different than it was at 17, except that I know more, have more stuff, have more money, and know more people. I guess I have slightly less physical endurance (although, not really), but rarely is that the primary factor for success.
