Please, before reading the article posted above by one of the new racist forum members, take a read to this disclaimer available on the same webpage: https://www.ncbi.nlm.nih.gov/pmc/about/disclaimer/
If you then read the article, it is easy to understand how a research that includes a 30 subjects sample and categories as not rigorous as "African American", "Caucasian", or "East Asian", is published there.
The only valid conclusion for this research is that the Black guys they chose for their study (only 10) tended to sweat more.
Racism, ignorance, and stupidity always parade together.
