It's cool.

3 year old: What first letter of alphabet
Mom: It's A duh.
People who only eat sushi and think they're healthy, be on the internet for 10 hours and think they're better people because they drive hybrid cars. They also probably have around five partners and don't want marriage or kids. Oh and, some of them are alcohol addicts. Also they have a weird obsession with Pokémon and Techno music.
Alan: Hey man! I just got a hybrid car! I will surely go to heaven for doing so much to protect the Earth's environment!
James: *sigh* Millenials...
Chemical formula H2S, also known as sulfane, dihydrogen sulfide and sulfur hydride. It is an inorganic, colorless, weakly acidic, flammable, highly toxic gas that smells like rotten eggs. It is found in trace amounts in farts which is why they smell so bad sometimes. These amounts are too small to cause any harm, as hydrogen sulfide can already be detected by the human nose at concentrations below 0.1 ppm. The famous chemist Carl Wilhelm Scheele was the first to discover and isolate the gas in 1777. The gas can be created by reacting iron sulfide aka pyrite with hydrochloric acid (any concentration). This should however, never be done even by experienced chemists. The gas is highly toxic and even in presence of a fume hood, harmful concentrations could still escape, and the gas wont really escape quickly from the lab as its slightly heavier than air. Also, even if the concentration was not harmful, who wants their laboratory to stink like farts? Nobody. Also it could minimally interfere with reactions. So please don't make hydrogen sulfide. Now, does hydrogen sulfide have any uses? Well, not really. It's only useful in chemistry and making some reagants, but other than that, it plays no role in everyday life.
Max: We accidentally made hydrogen sulfide and had to evacuate the entire lab....
Thomas: Seriously mate?
A newborn person that has just begun to explore the world. Some talk, some don't. The development of the human body also happens the fastest in this time, so the baby's age is mostly counted in months or even weeks in this time. People aged this young have no real consciousness, but show human characteristics. Not much to say about people aged 0.
Part of the Age Group: Baby
0 year old: Goo ga goo ga.
Marcus: Is this your son?
Thomas: Yeah, but he's only 0 years old yet, or 7 months to be exact.
The only movement that doesn't move.
Want to get cancer, heart diseases and liver diseases? Then join this movement. Oh wait, I forgot to say, it's women-only, even if most obese people are men. Oh sorry, how offensive from me. I meant to say plus-size.
Stacy: My life sucks. I want to commit suicide...but there are no bridges in the town...
Lucy: You can just join the Fat acceptance movement, they will give you cancer and dozens of heart diseases.
Stacy: Okay thanks!
