I'm 56 years old, and I have an appointment on Friday for my annual skin check, because melanoma is not something I want to have to deal with. Whether you are 16 or 56 or 76, please don't mess around with sun exposure. If something on your skin doesn't look right, have it checked out. And if you've ever had a blistering sunburn, make an appointment like the one I have on Friday. Your future grandchildren will thank you.
