Volunteer for aging and disease studies?

I feel like it is my sworn duty to do so. I’m 50, but I always win tons of junk at amusement parks when they try to guess my age-many people think I am in my mid-30’s. My skin is most definitely not that of a 50 year old man, to name just one specific aspect.

And I just fought off an attempt by the Fates to give me the flu-24 hours after I first felt the symptoms, aches gone, headache almost gone, stomach feeling 75%, still feeling a tiny bit weak (get dizzy when I stand up), but…the flu, people.

So surely there are some labs somewhere who would be overjoyed to put me through a battery of tests and such, right? But I have no idea how to find same. Pointers in the right direction appreciated.

Frankly, and I really don’t mean any disrespect, people have a habit of deluding themselves about this stuff.
I learned early on that if someone asks you how old you think they look, knock about 8 years off what you really think (obviously a bit less for the very young). Most people like to think they look younger than their age, and have an old-fashioned idea of what people should look like at particular ages.

In terms of your question, I doubt that there would be much interest in the scientific community.
You may find a study or trial going on at your local university that requires unusually young-looking older people. And if so, they may pay you a decent amount to take part – research with specific requirements for candidates often need to pay well to be viable – and sometimes can be fun.

I can advise on how to volunteer for such studies, but I’ll hold back on doing that for now because I think this may not be the kind of thing the OP meant.

Just a week ago I was walking thru the train station and people from the American Cancer Society were passing out pamphlets.

[…digging in my bag to find it…here it is…]

They are looking for volunteers for their Cancer Prevention Study-3.
Apparently they take some blood, and have you take surveys every few years.
They need people between 30-65 years old, who have never been diagnosed with cancer.

So if it looks like fun, go for it.
