I'm a programmer (cto these days) and a skateboarder (kind of c'os age is not just a a number) and I've always been in awe of people who smoke weed and are able to engage in either activity and yet I do have friends capable of such. This is not a lie :-)
I've seen it with my own eyes. What amazes me is how good they are at it. If, by contrast, I did same I would end up hurt or fired :-)
