"If you're hiking in cold weather and start to sweat, stop and remove some layers until you feel cool again."
"If you are going anywhere away from everyone who cares about you (whether on a hike or a date) let someone know where you are going, when you expect to be back and who to contact if you are not contactable after that time."
