Could thinking positively about aging be the secret of health?

I came across a very interesting article about aging and positivity this week. It talks about how studies show that those with a more positive outlook on aging and those who find purpose into their elder years tend to live longer. I'm curious if you all agree that your mentality can have a big effect on your health, and what ways you plan to find purpose in the coming stages of your life.

This is my last class with all of you, so I hope to see as many of you as possible!
