Long ago, I worked for an institution full of young men.
You could just walk around and smell the testosterone everywhere in the air.
When I mentioned this to other people, they looked puzzled...
Before I was diagnosed with metastatic prostate cancer and put on androgen deprivation therapy, I perspired, a lot. After an hour or so of being active, the odor was not pleasant.
Now, I can wear a polyester shirt around the house for two days, and no odor.
