We've probably all seen the survey in recent days, in which US residents were asked if they would want to live to be 120.

That's one hundred twenty years. A majority did not want to live that long.

How about you? Would you want to live to be that age?

I'd like to think I would, but there are some really big "ifs" involved.

If my health were good. If my loved ones were still around. If I didn't feel as though life, and the world in general, had passed me by.

I can only use my own father as a guide. He lived to be 95, but most of his contemporaries were gone. My mother was gone. He didn't understand a lot of what was going on in the world. And if he had been asked, he would have said he did not want to live to 120.

Up until a few months before he passed, he had an older sister, who lived to be 101. He would always say "I hope I don't live that long. It's too old."

Bear in mind here that 120 years is just a little less than twice my current age, and while my health is pretty good, I'm not the most robust guy in the world. So I'm really stretching it here.

But if my health holds out, I'd like to see what life is like 58 years (!) from now.

Still, it's out of my hands.
