If you were given $100,000 to start a foundation, what type of foundation would you start?

I think I will start a foundation to help the old people who has nobody to rely on. Nowadays, the birth rate is getting more and more lower. And the age of the people who live alive is getting more and more higher. This will cause that when people are too old to take care of themselves, no one else could take care of them. So I think if I get $100,000 to start a foundation, I will establish a foundation to take care of these old people who need to be helped.
