Everyone has that one thing they're freaked out about relating to their own health and mortality. For me, it's diabetes. I had a teacher in college who lost one foot, then a leg, then another foot, all to diabetes. It eats your body. And... the most painful thing... a lot of times... it's a lifestyle disease. What you put in your body, and what you do with your body, has everything to do with this disease.
I was once asked to drive a diabetic person to a routine health screening. They looked up at me terrified and asked, "What if it's cancer?"
My brain answered, "Cancer? I did cancer. Cancer can be easy. What if it's diabetes?!"
There is a giant study the American Cancer Society is conducting. It's called Cancer Prevention Study-3. That's a link you can click if you want to check it out. I learned about it during a volunteer training a few weeks ago. The friend next to me nudged me and asked, "Did you sign up yet?"
"No. I don't qualify."
"You can't have had cancer already. And I've had it."
"Aw, your cancer didn't count. Oh, I mean, I'm sorry. That was rude."
"No, dude. You just made my day."
