Pro-tip: A nice smelling candle is nice. A nice smelling candle is no replacement for keeping your living space clean and also opening all of the windows from time to time to let the whole place air out. Personal Comment: I've fallen in love with pine scented candles myself. In fact, I have a pine scented air freshener in my car right now.
We have room inspections every morning so our room is absurdly clean for 3 freshmen living together. The freshmen themselves, however, are another issue. Fresh air and daily showers are but a band-aid on the great stench of Room 647.
Yea. Young dudes are the worst. My record was a little over two weeks without a shower, in the height of summer. I smelled so rank and disgusting that I broke through to a side where I smelled pleasant again (to myself). Have you ever had a bag of funyuns? That fake onion ring chip? I smelled just like 'em. Fifteen year old me thought I was the shit.
Pro-tip #2: Stick with one scent for your candle, especially if you have carpet floors. Experimented too much with those myself, then had the bright idea of masking those smells with burning incense.... I took advantage of my apartment's changing out the flooring this summer and got a new carpet installed after that whole mess.
