As I get older and the more I feel the pressure of mortality the more I am interested in trying a variety of activities. I don't have to be the best grappler or the best shot. I want to learn a new skill, even if it is at a basic level of proficiency. I just want to know what it is like to be a rider, a grappler, a polo player.
In any case cross training is good - keeps you active and not bored with your training.
