For the second point I'd suggest going to a shooting range or martial arts classes. Shooting ranges can be surprisingly cheap, and both can be very fun.

As much as we try to separate ourselves from it, we are angry, filthy apes. We are predators in the animal kingdom, and we didn't get to where we are without determination and violence. Indulging that part of ourselves in a safe consentual way is healthy, such as through video games or physical exertion. Plus with either suggestion you're learning a skill that may save your life in the future, either by fighting, being strong/fast enough to run, or just being familiar with firearms and how to handle them properly.

Probably a little late to ask, but how physically taxing can welding be? I'm very interested in joining a trade school for this, but have Marfan Syndrome and have to be careful of how much physical stress I go through...
