You can use substances without abusing them. I'm sorry that your uncle was an alcoholic and you probably shouldn't drink heavily if your family has a history of alcohol abuse but there are many more people who can drink and lead successful lives than there are alcoholics.
If you can't handle your shit... good for you don't drink but there are tons of positives to drinking if you're able to keep it under control.
Here's a tip: instead of wearing an avalanche beacon just put a dog treat in your jacket.
That way, when the search and rescue dogs find your body, they can have a little treat.
Leave no turn unstoned.
