Well, where "screwing around" == killing. Screwing around by taking probiotic supplements, eating fermented foods, etc. is generally considered to be good, or at least harmless.

The stinky hypothesis is interesting, I would think it would require an experiment designed around the use of deodorant soaps (which often contain anti-microbials). We know of course that people who wash very rarely often do have a distinct odor, though there's at least some implication that diet plays a part in exactly how stinky it is.

As an anecdote I gave up antiperspirant and deodorants after suffering rashes and pain in my under arms. I sweat more, but I was surprised to find I actually smell better. Or rather I'm told I smell better. Additionally I discovered that the stains in the underarms of my clothing went away, apparently it's caused by the deodorants. Diet may indeed play a factor, I am vegan. YMMV.
