@Wisedly33: I'm with you. The higher the SPF, the better. In fact, I've made it a point to stay out of the sun my whole life, and my skin shows it.
I have cousins who are just a couple of years older than I am who were real sun worshipers in high school and college, and they're paying for it now. I look at least 10 years younger, and that's not vanity. Not many people guess my age within 10 years of the actual number. I have had a couple of painful sunburns and that taught me my lesson about always wearing sunscreen.
Also, I usually wear a hat or cap when I'm in the sun. A scalp sunburn is no fun, whatsoever.
