The feeling of being a tracer is indeed good, as many others have mentioned. However there are other facts involved as well, which are more nuanced From my point of view, I will give some details:
We experience the world in a playful manner - In this 3-dimensional world in which we live Parkour changes the way we interpret, understand and travel. Basically the entire world is our playground. The more new movements we explore, the more opportunities we begin to see. Clearly worldly behavior like stairs and street crossing can now be creatively approached. As a consequence, life, for a tracer, is much more fun.
We actively optimize our body and mind - Unlike popular belief, parkour is not an awkward sport that shows and reveals the ugly stunts. This is only a flashy side, which is media-conscious. Traceurs usually make efforts to make seemingly unsexual conditioning and training in hours and hours, such as quadrupedal movements, one-foot balance, repeated movements, etc.
These exercises ensure that our bodies become stronger, longer-lasting and less likely to injure themselves so that even when we are 60, 80, or even 100 years of age, we can remain an active tracer. Isn't it a great sensation to think that at that age it could still be very nice? There is also some training in which we confront and better manage our mental obstacles (e.g. fear, ego). Actually, practicing parkour is more a self-improvement process than anything else.
We are often misunderstood to be a reckless public nuisance - I touched on how Parkours is popularly considered to be a slow, dangerous sport in my previous speech. It is this misunderstood conception that traceurs must constantly combat so that we can really be accepted as who we are rather than examined based on what the public assumes we are wrong. Sometimes we are accused of trouble, dangerous actions or even infringement. A tracer who embraces Parkour's original values will demonstrate that we aim always for a peaceful group, to leave no trace, to be more mindful and respectful of ourselves and our community and beneficial to society. Public scrutiny is not easy to handle.
We constantly learn more about our body and mind - We know more about our limits and what they are capable of, and how we think and feel, every new step we make. This self-awareness and sensitivity is vital to a practice such as parkour because it can be fatal to fail to pay attention to our bodies.
