One of the things that I have been considering doing is rock climbing. It always fascinated me how people can climb vertically on shear cliffs and rock terrain. It's an activity that has numerous benefits and it also happens to be an excellent way to get your upper body in shape. More so, I think we can all benefit from being able to climb.
Modern day people don't really need a reason to have the skills to climb, hell, we don't even need to be able support our own weight. What was once a fun activity to do when you were a kid, now it really isn't cool to climb something unless it is within a narrow band of things. I used to love climbing trees and certain buildings, although it wasn't necessary safe.
I primarily want to learn to climb better because of the challenge and the exercise, but also being able to save yourself in a dangerous situation is a plus. I also yearn to do something more primal to man, which is to conquer its surroundings. So for now I will start to plan some rock climbing days into my schedule.
