I can understand why you're happy about
having a tan, because it means you're outside in the sunshine enjoying life.
Living in Florida, I can always tell when someone has just arrived from spending the winter up north, because they're skin is so white. I can also tell how long they've been here, because by the first week, they usually have a bright red sunburn!
That's how they discover the importance of sunscreen, and it takes them a couple of months to figure out how to balance the right SPF with the right amount of sun time before they achieve the much-desired bronzed tan.
Enjoy your healthy glow!
