human is perfect in it's own, modify it and that's what you got
balls being too detached from the body means testicular torsion can occur. at complete random as well might i add. for any who don't know testicular torsion is when the cord that provides blood to the testicle gets twisted and the blood supply gets cut off. end result without treatment is the testicle developing gangrene and at that point its "your sack or your life make a choice."
a Woman has to pass a baby several times the size of the orifice its supposed to come out of, often resulting in hemorrhaging blood and in many cases doctors have to cut you open just to get the baby out. Viva la C-section! am i right?
The appendix is a worthless leftover turned ticking time bomb of death. if that puppy blows pray to what ever you believe in
that you got a hospital nearby cause 36 hours without treatment and you are gone.
for those that don't know your appendix is this little worm looking end-cap on the end of your large intestine and if it gets clogged which can happen at random pressure builds up causing it to swell and cause excruciating pain until it finally bursts spewing fecal matter all over your organs which if not flushed extremely quickly will cause infection and ultimately sepsis at which point you are done for.
you think these things are perfect? no evolution always at BEST half asses things to the point of "good enough" once
"good enough" is reached evolution peaces out until the next dire problem crops up. at worst? well look at the koala
koala evolved specifically to eat a leaf poisonous to every other herbivore and have their diet revolve around it. this leaf also happens to be coarse and it grinds down their teeth over time and these teeth mind you DO NOT GROW BACK so before they can die of old age they have ground their teeth down to nothing meaning they can no longer eat the eucalyptus leaf meaning starving to death is their natural cause of death.
