I often see challenges on Youtube that make sense, and others that are really absurd. The other day I happened to see one guy going with his bike over the edge of a very high dam and another - very well known - traversing a tennis court over the net on his bike.
Now, while the latter however is a sign of great skill but not of a desire to kill himself, the former is really, in my opinion, a big, stupid nonsense.
Unfortunately, there are dozens and dozens of clips on Youtube of people doing unnecessarily dangerous things, where the risk is not related to the lack of skill but to the situation: narrow routes over cliffs traveled at high speed and without any safety, jumps in uncontrollable situations, where a gust of wind is enough to kill you.
Does this really make sense?
That's fine, long live freedom of choice when you don't harm others (except your loved one when you loose your life, or the risk associated with the recovery of your body in case of accident in remote areas). Unfortunately, however, these kinds of videos incite people who do not have the required skills to emulate them, and that is bad, really bad.
I personally have no stories of big falls while going uphill to tell. Only the occasional fall almost from a standstill, often because to get over an obstacle I had to set turbo. In that case it is difficult to control the pulse of the engine well. As a result, I sometimes happened to lose my balance and fall sideways or backwards, without any damage except for some crass laughter from those who saw me falling like an idiot....
