Nowadays it is too dangerous to stay long under the sun. Your skin would be greatly affected by the ultraviolet rays emitting by the sun. When I was a kid, I remember that we used to play under the sun up to 10 to 11 O'clock in the morning and we couldn't feel the heat of the sun much. It is the same with in playing in the afternoon. We were still playing unaffected by the sun rays at 3 O'clock in the afternoon. But now, we couldn't stay long up to that time.
