Gives a whole new meaning to "brain food".

A recent study by scientists at Johns Hopkins Medicine has found that hydrogen sulfide, the smelly gas released during flatulence, could protect aging brain cells from cognitive decline and Alzheimer's disease.



The research was published in the Proceedings of the National Academy of Sciences and highlights hydrogen sulfide's role as a key signaling molecule within cells, affecting processes associated with aging and neurodegeneration.

There is a downside, H2S is very poisonous.

You should have saved this for the first of April. It would've made a lot more sense then.

Somewhat poisonous, but in my day it was widely enough used in school chemistry that most labs had a Kipp's Apparatus set up for making it.

No, very poisonous.

The problem is that in high concentrations you lose the ability to smell it.

Sounds like an advantage to me! :-D

But seriously, as Paracelsus told us centuries ago, the dose itself is the real poison of any substance. Naughty kids were able to buy stink bombs up until the mid 1980s when the Thatcher government banned them (but not over health fears it must be said) and they released the powerful stench of H2S when crushed under foot. So it's harmless in low concentrations.

Gives a whole new meaning to being called an old Fart. It’s self preservation now

You are easy to associate with noxious odors.>

I'm so glad we got to teh bottom of it......

I'll let my wife know :)

I almost never eat at White Castle because I don't want to inflict that on my dearly beloved.

A friend of mine at Uni claimed to have a schoolfriend with the most rancid farts who collected farts in the bath in a jam jar then released them during assembly on the final day of term.

I tried that , the jam jar bit when I was around 13. ISTR it didn’t really work and the odour had weakened considerably on opening. However doing a really potent one into the intake of a ventilation system into a ships engine room and hearing the engineers blame each other was quite satisfying .

A church that I used to work at had a small kitchen, and on my dinner break I was frying up some chicken. I'd had a bunch of White Castles with extra onion for lunch, and was farting up a storm. The whole kitchen smelled strongly like White Castle. Unexpectedly, one of the church members showed up, and came into the kitchen. He looked at the frying chicken and said, "Smells good." I said, "Thanks." Yeah, it smelled a bit like frying chicken, but mostly it smelled of WC farts.

He was a very nice man, and was trying to be nice. Maybe he did think it smelled good, but how could he have thought that frying chicken could have smelled like that?>
