a climbing contradiction

So I'm at the gym today, the pool is still closed for unknown reasons, and I'm at a loss as to how to get in my cardio.  Running and I are still not friends, I get bored on the bikes, and, let's be honest, those little seats are just not comfy, and I lose feeling in my feet when I'm on the elliptical.  So, by default, it looked like the stair treadmill thingy was my machine for the day.  So I'm climbing and climbing and climbing and I notice the guy next to me has two water bottles.  My first thought, was whoa - way to stay hydrated!  But then, as I continued to covertly observe my climbing buddy, I realized he was not the epitome of hydration, but rather a climbing contradiction.  The second water bottle was in fact his spit cup!  Can we say gross?!  I was just floored by the fact that someone who'd been climbing for as long as he had been, and at that pace, was actively polluting his body with chew....  I mean, really?  You can't wait an hour until you're done in the gym?  The rest of us have to see it and smell it too?  It was a particularly nasty experience, plus pretty soon I was grossing myself out as I started dripping sweat.  They must turn the heat up higher over by those things because whoooo Nelly - I was kind nasty.  But, nasty in a oh yeah! kind of way :)
