I am that anomaly. I change my shirt twice a week, not because it smells but because it gets dirty from the environment (spills, rubbing against something etc).

I am that anomaly. I change my shirt twice a week, not because it smells but because it gets dirty from the environment (spills, rubbing against something etc). It takes about 7 days of no showers to have a noticeable smell. However I prefer showering daily or every other day because I enjoy taking a shower at the end of the day. I also don't need deodorant. I used it once as a teen and saw no purpose for it.
