Re-Entry Thought #12

Ah! I feel like I'm in a constant airplane cabin. What I mean is that I feel like all the moisture in my body is being sucked out by all the heating and cooling going on and the fact that 95% of my life seems to be inside a building or car. I know I'm complaining, but doesn't it seem unhealthy to spend that much time inside? Granted I am a student, so much of that time is in the library over books or in a classroom. But, wouldn't it be healthy to travel by foot now and then on a subway or bus... plus wouldn't that help with air pollution and pollution in general? Just a thought. I do know that I'm on my soapbox. And I'm still presently in the hermetically sealed library writing papers and reading. I don't think I'll ever fully get used to the air-conditioning and extreme temperature changes instead of having nice open windows (without screens).
