If you're from the cold climates, I understand.
I have lived by the beach or the ocean all my life, I will use a lot of sunscreen when I do go fishing, swimming or surfing but I usually try to avoid the sun as much as possible. Everything I've seen and read, the damage sun can do to your skin is not good.
Yes, you can get vitamin D from the sun and it's important for your circadian rhythm getting sun burned is not healthy....
