Jack don't know shiiit!
OK, I only read half the replies, not because i was running out of energy, but because I had to get it off my chest. Jack, you are full of crap! With age comes experience, with experience comes knowledge, and when you know what the hell you are doing, the stress level drops. From what I see, the young inexperienced ones have the stress if they care at all.
We older guys stick with the problem until it's resolved, most of the kids want to bail as fast as their limited experience can take them. If it weren't for Google, they couldn't fix most of the problems that come their way.
So before you play the friggin age crap again, think about how many old people you might piss off. We may have the answer you need!
