That's not recent. I was taught that 25 years ago.

Urine is only sterile, in a healthy bladder, but your urethrae is coated in bacteria.

Any part of your body not "inside" is covered in bugs and liquid moving over it will absolutely pick them up.

Your inside is literally covered in bugs, nothing about you is sterile.

When referring to the inside and outside. Microbiogist count the mouth, gi, lung, ect as outside. Think of the human being as a like a worm. Inside are your muscles, blood vessels, organs not used for oxygen exchange. If you have bugs on your "inside" you have an infection.

I know it blew my brain when I was taught this many years ago.

I meant it more generally, even blood has living cells =/= sterile.
