My take on this is.....
With todays life, mortgages, marriage, children, bills, financial worries, politics, crime, road rage and the list goes on. All attribute to STRESS, I think with all we put up with today and always putting yourself last kills us all a little. Riding the bike (when you can), and enjoying the mateship of similar minded people put's a little bit of life back into the tank. I don't see it as risk taking as much as I see it as a pressure release valve and a incentive to have some enjoyment of life amongs't all the bad stuff.
