If it is cold on the valley floor, move to higher ground.
It's not always a good idea to move to higher ground. Note that there is a higher cold wind and it may be harder to start fires. You'll just have to use your watch out.
Always swim parallel to the shore if you are caught in a rip current.
Some of the rip currents are diagonal and some are longshore ones. Swim perpendicular to the rip in the same direction with wind or ocean current. If you feel that you're swimming upstream, this means then you're moving in the wrong direction.
You will suddenly find yourself in a survival scenario.
Survival situations do not always happen suddenly. They are typically the result of a series of wrong decisions. Often it is your pride or insistence that gets you there. If you are out fishing and you see lightning, get off the lake. Don't be too presumptuous and most likely everything will be fine with you.
Survival is about knowing what to do.
Any survivalist will tell you, survival is much less glamorous than just having the right skills. Usually it is simply about prevention. Be smarter and use common sense. The best way to survive is not getting yourself into a deadly dangerous situations.
You should play dead if you meet a bear.
It depends on the bear. If it is a grizzly then stand your ground and when it makes contact drop down, cover your vital organs, and pretend dead. If it is a black bear, it wouldn't help you. Vise versa make yourself seem big and threatening by using your clothes, screaming, and stomping. However, don't make eye contact.
