Sunscreen

I just read an article about skin damage from sun and the importance of wearing sunscreen. Those of us who have had melanomas removed know we must protect our skin. BUT I did not know this:

Apply enough sunscreen to fill a shot glass (about one ounce) in order to thoroughly cover all of your exposed skin. During a long day outdoors, one person should use about one half of a full eight-ounce bottle of sunscreen.

WOW.
