Reply to comment by SleeplessTaxidermist in TIL When a cow has opposite sex twins, the female twin is usually born intersex and infertile. This happens because the twins blood supplies are linked, which exposes the female to male sex hormones. by awawe

It's more common in the dairy industry because of the genetics and also more likely to be with a i or embryo transfer. Most beef cattle is live cover, AKA the bull does the job. Therefore, a life cover is more likely to not give you twins.

A few percent of people are asymptomatic carriers of MRSA in their skin microbiome. MRSA can kill if a few things go wrong at once. It usually sits there being dormant or causing transient infections like pimples, because Staphylococcus aureus gonna S. aureus, but it can sometimes get into your soft tissue and lungs and blood and then kill you if not adequately treated (and adequate treatment is hard because MRSA is immune to a lot of our favorite antibiotics).

Reply to comment by biskmater in TIL That the character who first said the phrase "fortune favours the bold" - Turnus, in the Aeneid, spends the rest of the story suffering military defeats before he's killed and heads to the underworld, miserable, at the end of the last book. by Equal_Caregiver_4909

A when A. In addition it is also apparent that being lucky causes boldness on its own and vice versa: a person who often succeeds is eager to try, someone who fails more than their share is going to be hesitant with even little risk.

Reply to comment by CanadianGurlfren in TIL that between 1895 and 1908 the population of the Belgian Congo declined by between 2 and 13 million due to colonial brutality and diseases caused by colonialism. by hetkleinezusje

Yeah, I assumed that would be it too, but I checked and for reasons I'm not highly educated enough to understand, the Latin plural of "census" is "census" (unless its in the genitive case, in which case the plural is "censuum", which seems pretty rad but not strictly relevant to this usage) and thus in English the rarely used "proper" plural is too. Maybe it wasn't originally considered a countable noun? That'd be kind of ironic.

There's only seven keys we need to use on the keyboard and they are far cleaner than the rest because of it. It's annoying when someone wipes the sawdust off as I can remember the inputs at first

Phones especially, people bring those everywhere.

Plenty of people jerk off to internet porn, phone in one hand, dick/vagina in the other. Your phone is covered in all sorts of bodily fluids. Maybe you wash your hands (and that's a big maybe), but you're not washing your phone.

Literally everybody brings their phone into the bathroom. Everybody surfs the web while they're taking a shit. Your hands are covered in god knows what, and then they put the phone down on the nasty-ass fucking counter, wash their hands (hopefully), and immediately pick it back up again. Why bother washing your hands if you're not going to wash your phone?

People bring them into the kitchen to follow recipes. Cut some chicken, scroll to the next step, wash hands maybe, dice some onions, scroll to the next step...
