Sun

How is it possible that I'll sunburn myself walking around Lake Calhoun at 6pm after having covered myself in SPF 40 sunblock but laying on the beach at 2 pm WITH NO SUNBLOCK ON doesn't even make me pink?

So, I am just as pasty in my brand new swimsuit as I was when I tried it on. I am just as chubby but I have decided to not let that stop me from wearing it.
