Well - not the smell (though it is getting hot lately), but the amount of work I have to keep up with handed by our lovely university. Right now, I'm trying to finish the grammatical errors of a group member who has "finalized" a project. Not that I mind it (since I hadn't done much work myself) but when you have a backlog of tons of things (and when you're trying to make an attempt to be regular at your blog, things don't sum up that well).
Work stinks. The university stinks. So do my teachers - and the guy who travels next to me in the van (he smells!)
Need a way to beat the heat? First of all, travel in an air conditioned vehicle. Next, look everywhere but your university (or office, if you're employed). Thirdly, settle down for watermelons (no, I'm not hinting at anything...) - they're a good fruit for the summers.
Or go have some ice. Does the same thing, but for free!
