Trends come and go the same way fads do. What is going to kill
mountain biking are all the deaths and injuries. Mountain biking is not
considered an extreme sport, yet it racks up deaths and injuries just like most
extreme sports. The vast majority of people in this world do not want to risk
life and limb for a mere recreation. Only an extremely stupid minority of fools
want to do that.

Well, IF there were all these deaths and injuries then you might have a point. However, the statistics don't back you up ... Mountainbiking is relatively safe ... a rate of 1.54 per 1,000 exposures is less than soccer, rugby, american football, road cycling etc etc etc. (http://emj.bmj.com/content/early/201...9.086991.full).

So, once again, you're incorrect; mountainbiking produces injury and death statistics nowhere near 'extreme' sports.
