Old enough that it doesn’t matter.
Got bored with CrossFit. Wanted to do something more dynamic with jumping and higher risk. Most importantly it had to be fun. Had heard of parkour years before, searched for groups that trained in Boston, and found Parkour Generations.
Parkour to me is like playing. I love to be able to creatively move through my environment, which is also a reason that I was a passionate skateboarder for many years, and why I continue to ski.
Parkour has reinforced my understanding of the different levels of thinking in my brain. Using too much rational thinking in parkour can be dangerous: e.g. considering the risks of balancing at height, or imaging the different ways I could get injured during a movement. I know to shut those thoughts out and just go for it, granted I know a certain maneuver is within my abilities.
I have learned to trust my instinctual judgement of distances and speed required, etc. It’s quite amazing what the human brain can evaluate without rational calculation. My experience has led to me having very good grasp of what I am capable of, and what I am not. This confidence in my abilities is why I have yet to suffer any side-lining injury.
Another thing I love about parkour is that it makes me feel true physical risk; it makes me feel alive. I enjoy putting myself in situations in which my physical abilities are the only things keeping me from suffering major damage. Example: balancing at height. Living a vanilla life of driving to work, sitting at my desk all day, then heading to the gym to use the nautilus machines is too safe. It is not the life I choose to lead.
I live in the Netherlands now, and don’t train parkour much because I haven’t yet met a group of people that train near me. But I still engage in risky physical activities that require strength, endurance, and balance. They are slacklining, rock climbing, and survival training (a Dutch variant of obstacle course racing).
