Very very true. And it doesn't matter what specifically you're doing -- whether it's snow sports, hiking, river rafting, flying, jogging, etc etc etc. The idea is to be doing something that takes you outside your life for a few hours. While I'm on the lift or on the run I'm not thinking about mortgages, projects at work, my daughter's braces, or anything like that. You need to spend a certain percentage of your life doing something that has no ROI, no goal other than what you set for yourself, and otherwise no redeeming objective "value" outside of the deed itsself. This is zen.
And you will live longer, and enjoy it more.
On the contrary, I find riding to be a huge ROI. If not for snowboarding I would have been Xanax-ed up to my gills by now. And that shit costs a ton.
