The biology class I'm taking is both simple and challenging for me. Science makes sense to me, but I need to really listen, write it all down, read it out, re-explain it, think it through to get it. Very nerdy, yes.
We received our grades from our first test - a tough set of essays and a rather random mix of true/false question. Out of 112 points possible (including bonuses) I got 100! An A!
After looking over the tests we started learning about antioxidants (we're done with carbs, proteins and fats). We learned about how evil, yucky ozone and other nasty free radicals which cause aging, disease and just mess up your cells like crazy. Antioxidants come in berries, avocados, coffee and other good stuff. Free radicals come all manner of cells that lose an electron.
I'm still learning about antioxidants, so I might not be spot-on about every bit of this. But I do know that the ultra-violet radiation from the son gets wrapped up with ozone and causes skin cancer, wrinkles and nasty damage.
This means I'll keep spraying SPF 45 while I'm outside, continue to slather myself in SPF 40 every morning (rain or shine) to kick these free radicals' tails. You should too.
Pass the SPF 50!

When we were in Costa Rica she used SPF 75, the existence of which I had not previously been aware.
Anything higher than 45 is just silly.
I don't buy SPF 100+, but it is available.
Fact is, you have to reapply regardless. Keep yourself covered, friends!
