So really how much UV exposure per day is safe?

Question

Well I just got back from the first day of senior high today, all the buildings are seperated so I have to walk in the blazing hot UV index 10 sun. I was wondering if I should go to school with sun screen on everyday since I walk a few minutes between classes in the sun. Porbably about 2-3 minutes between classes for 7 periods which adds up to about 14-21 cumulative minutes in the sun. When I get home though, no sun for me. I was wondering if this is a safe amount of daily exposure? Am I just worring too much lol, because I'm one of those lucky guys with a "clean" face, I dont want all that sun damage showing up >.<

You're on "Yahoo" answers and you're telling me "Google" is my friend? Anyways, that wasn't very helpful >.< But thanks anyways I guess
