Unprotected Sex!

The odds that a Pregnancy will result from a Single Act of Unprotected Sex are approximately 1 in 25 (0.04%)

Don't let this be YOUR future child...

Whoa, kids. I know what you're thinking. Hot shit! I can have unprotected sex twenty-four times scott-free before I even have to worry!

Well, sorry to burst your idiot bubble but if you think that then
1) you suck ass at math and have no idea how probability works
2) you should start thinking of names for the idiot child you're about to have (I'ma call him Biff)

For the rest of you, let's break this down.

Basically this is an issue of timing. Now, full disclosure: I'm not a scientist but I have it on good authority that boys have penises and girls have vaginas. Now, to make babies... I don't know, but a woman can only get pregnant on approximately 2 days in every 28 of their cycle. But then she also needs a dude's spermatazoa to eat the egg or whatever and those little fuckers can only survive for around 2 days once in her stomach. This gives us odds of jot, scratch, erase = 11%!

But even if these two windows do happen to overlap after your shitty Junior Prom in the back of that shitty Pinto, there's some good news: Sometimes the spermatazoa don't always eat the eggs! In fact, when together they only do their thing 1/2 to 1/4 of the time they're all chilling. This drops the odds down to between 3-5% that you'll have to explain to your son (Biff) that he was the result of a drunken irresponsible and horribly awkward night for everyone.

Seriously though, 3-5% is a lot. Like 85% odds in the first year if you keep at it, but whatever, it's your life to roll the dice with. Consider yourself warned so don't bitch to me when you're rail-roaded into marrying said girl you brought to J-Prom who now resents you cause you got her preggers (and you didnt't even wanna go with her!) and then have an idiot son named Biff who sucks at math. Good luck with that though.

Dental Suicide!

The odds that that a Dentist will commit Suicide in a given year are approximately 1 in 1,250 (0.08%)

We've all heard the 'fact' that dentists have the highest rate of suicide for a profession but is it true? Yes, yes it is. Why? Well after some extensive research and number crunching I'll try to break it down for you with a mix of actual evidence & my own harebrained theories.

Have you ever met a little kid who REALLY wanted to be a Dentist when they grew up? No. No you haven't because all children (and most adults) hate the dentist. And doesn't that suck to go to work every day trying to help people's oral hygiene while knowing most patients hate being there and you make kids cry? Not much positive reinforcement which probably wears on you.

If so few kids aspire to Dental fame, who becomes a dentist? I don't know but I imagine it's a pretty repressed group; The people who give up on their dreams for the safe steady paycheck. If you 'settled' for being a dentist and regret it, that's gotta eat at you.

The overwhelming majority of dentists are also white males which happens to be the demographic most prone to suicide. It also seems a pretty lonely job but who knows.

Finally, they have the means. Even though they don't seem to get as much respect or appreciation as a veterinarian, they did go to school and have access to all sorts of things. The rest is very dependent on mental health and individual tendency but these are huge red flags.

All those factors taken together put dentists at a much higher risk than average. Still, 0.08% seems pretty small huh? Well, when the average rate is about 0.017%, that makes dentists ~5x MORE likely to off themselves than a random person. Which is a lot so- brush your teeth, floss, and don't be an asshole to your dentist. Thanks.
