Did you use any type of sun block when out in the sun all those years?
Heck no...sunblock was against my religion, LOL. This was years ago before sunblock was even thought of. We slathered on stuff to make us tan more evenly, but it didn’t have any UV blockers in it. Our cure for sunburn was Noxema, LOL.
It’s a wonder I don’t have skin cancer because I would be a perfect candidate. I used to burn till I blistered when I was a kid/teenager. In addition to living in Florida our family spent a weeks on vacation at the beach each summer.
First MS symptoms showed up in college, so I was getting plenty of sun to that time. Of course once MS showed up, I found that my tolerance for heat was greatly reduced.
