Neither money nor space, and really the problem with the terrarium idea is buying off the Internet. Well, first, I wouldn't actually know what the terrarium is like or how it fits until it arrives, and second, I'd have to rely entirely on my googling skills to set it up correctly. I find this arrangement far from ideal... Just 10 years ago you could go and look and touch and talk in half a dozen stores around here, but everything's dried up.

But it's a better option than gym monetarily, and especially since one of the things I miss the most from the summer is the smell of fresh vegetation... or really any smell besides cars and dirt.
