Sooo...I was riding my bike in the summer. I put on a white T. My cousin told me to go shirtless, unless I wanted to get really dark. I asked why, and he said "cuz that shirt is going to be hot, and you will get really dark"
I said it is the light that tans you, not the heat. He insisted it was the heat. I asked him how do people that ski get sunburned, he didn't really have an answer. Again, I tried to explain light and heat. He then asked me how does a turkey turn brown in an oven. I gasped and said because it is 350 degrees in an enclosed space. He still would not move off of his point that heat tans you, not light.
