Example sentence: It was the summer of 1968 or so, and Dad and my little brother were out camping. While up in the mountains, my brother was bitten by a rattlesnake. As they raced back to the base, my dad sucked out the venom and used his hands as a tourniquet and probably save his life, for it was a serious bite, and he was just a little kid.
