Here’s why gym clothes smell so rank, and how to freshen them up. The science of stink.

Rancid gym stink comes from a concoction of oily sweat, bacteria, and synthetic gym wear.

▼ Whether or not you’ve resolved to get into shape this January, Muscle  Monthis here to teach you a thing or two about stretching, contracting, lifting, tearing, gaining, and so much more.
There’s an episodeof 30 Rock where Tina Fey’s character, Liz Lemon, lugs around her dirty, rancid gym bag on the subway, creating a protective stink bubble, so people don’t bother her. As a New Yorker who strongly values her personal space—paradoxical, I know—I’ve occasionally considered adopting this method.
But time after time, I remember just how foul that gym-clothes stink can get if you let it fester. And sometimes, especially with clothes made from synthetic fibers, unpleasant odors linger even after multiple washes. All of this begs the question: Why do gym clothes stink so badly? And what can we do to to freshen them up?
Why do my clothes stink?
Well, to understand why your clothes stink, you must first understand whyyoustink.
OK, fine. Why doIstink?
It all begins with sweat, of which humans have two kinds: eccrine and apocrine. Eccrine sweat is plentiful, watery, slightly salty, and it doesn’t really smell bad. You secrete it all over your body, unlike apocrine sweat, which only comes from glands in your pits and your groin. Apocrine sweat is the nasty stuff—a thick, oily fluid made up of fatty compounds.
But apocrine sweat still doesn’t stink on its own. Your skin’s microbiome— the cast of bacterial,  fungal, and viral characters living  on you right now—loveto eat those fatty, oily compounds in apocrine sweat. And the molecular leftovers of that feeding frenzy are what stink. That’s how B.O. is made.
Your skin’s microbiome eats stuff to create other smells, too. Lucy  Dunne, an apparel engineer at the University of Minnesota, says bacteria also eat dead skin cells. “They are specialized in what they consume,” she says. “That’s why your feet smell differently than your armpits. It’s also why your feet smell like cheese—it’s the same bacteria eating your dead skin that turns milk into cheese.”
Those B.O. molecules get on my clothes and make them smell bad, right? (▪ ▪ ▪)

Is that according to the scientific method, or the empirical method?

My frequent, empirical testing results in stink 100% of the time ;)
You, however, may not have the genetics to smell it...source

Everything depends on the object or person that emanates the smell, for example, communists and tyrants stink of retrograded and stale ideas, and I can smell the stench of them miles away.
But my nose is very sensitive to chocolate, I can trace chocolate like a bloodhound.
I prefer the artichokes over the asparagus, they are more delicious.
Have you ever eaten ceviche?

Love the cerviche and have enjoyed all over the world.
It was great along the coast of Baja, Mexico, but YouTube says I need to experience Lima, Peru.

In the USA there are many Peruvian restaurants, and in Lima there are also very good ones... But in my experience, the best ceviche is that oneself prepares... And definitely, the ceviche has the simplest preparation in the world:
