Let me get this straight...are you saying your Left doesn't smell Right...or that your Left smells more Right?
NO There does not seem to be a difference in the amount of sweat, just in the odor. I am reasonably certain that this has to do with a difference in the microbes living on the skin beyond that I am clueless.
Related but irrelevant comment. Years ago when I was a genetics student, our professor started a class experiment based on the everyday observation that after eating asparagus, some people smell it in their urine while others don't. Question: is the way they metabolize asparagus the genetic determinant, or is the determinant different smell receptors? The obvious experiment: eat asparagus, smell your urine than exchange urine samples and see the result. A clever set-up but one that caused a class-room rebellion. Unsurprisingly, of course. (Science falls to social niceties once again!)
I'll bite pattern? WHY? Why do you think that? (probably difficult to see a pattern when you are in the middle of it?)
Maybe there isn't one. It's just an impression; maybe I'm imagining it. Look back over the past month and see whether you discern a suggestion of extreme boredom. Your own perception is all that really matters.
I'm just new to this website (joined-up today), but I'll risk posting my first response on here here [any fans on here of Gertrude Stein's brilliant literary invention of repetition?]. The great thing about Science is that in 'doing it' one starts out with the simplest explanation first; reaching it by working from First Principles & going forwards from there. So, does Sculptor have a significant difference in physical & chemical microenvironments (humidity, dioxygen level, temperature, saltiness, etc.) between his two pits, perhaps occasioned by his job-type (or hobby) leading to the preferential & regular squeezing of one armpit more than the other? Skin microbiota populations & cell densities & proteomes (e.g., respecting catabolic processes in particular) can easily be affected by tiny differences in local parameters.
