H2S is nasty stuff... You start smelling it at a concentration 1ppm. The maximum allowable exposure level is 10ppm. @ 20ppm you get irritation of eye, nose and throat areas. At 50ppm, you lose your sense of smell (and therefore your main indicator that you're exposed to H2S), get a headache and dizziness. 100ppm is IDLH (immediately dangerous to life and health). At 500ppm, unconsciousness occurs within a few minutes, followed by respiratory paralysis. If not rescued by someone with SCBA gear within 3-15 minutes, you die.

I recently visited an oil field in west Texas where there was a big sign in the operators' building that said, "H2S: THIS GAS WILL KILL YOUR ASS"

Why would there be bed sores in the absence of gravity?

I believe they were saying that H2S could have some good implications for victims of heart attacks. My recollection might be wrong, but I think they were alluding to paramedics being equipped with the stuff to keep you alive during transport. You could probably find it on economist.com, let me know your results.

Hydrogen sulfide can affect several different systems in the body. Exposure to lower concentrations can cause eye irritation, a sore throat and cough, shortness of breath and fluid in the lungs. These symptoms usually go away in a few weeks after exposure ends. Long-term, low- level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory and dizziness. Breathing very high levels of hydrogen sulfide can cause death within just a few breaths. There could be loss of consciousness after one or more breaths.

man you really know how to sap the fun out of an article!

To paraphrase Dave Atell, you could use some lemon scented spray. But you just end up with a lemony-ass smell. And nothing beats ass.

Beans, beans the life-extending fruit
The more you eat, the more you toot
The more you toot, the longer you live
So mash me up some beans and feed me through a sieve.

What kind of suppression are we talking about? I mean, personally I think sniffing sewer gas would definitely shut off my appetite, which probably slows down my metabolism, but I'm having trouble believing it's anything close to a situation where I could stay asleep for a year.

I think it would be impossible to suspend animation completely. You would still have to stick all sorts of tubes and needles into the astronauts to feed them and antibiotics, so that they don't die of infection from bed sores, etc. Then, how do you cope with the massive muscle loss that comes with not moving for a year? You'd have to shock their muscles with electrical impulses to slow down deterioration, and how do you shock them without kicking them back out of the coma?

I might eat less and use less oxygen for a year, but I'd be in such worse shape than if I was just awake on the spacecraft.

Maybe the mice are just pretending they did not do it?...

Scientists have discovered that small doses of Hydrogen sulfide put mice into a completely reversible state of metabolic suppression.

i wonder what the upper limit on this state is though? i mean are we talking a few days? months? years? centuries?

makes a pretty big difference concerning usefulness.
