Randy question. What's one thing every BJJ practitioner just accepts as normal?

Meaning, I'm still fairly new to BJJ and I'm sering there are a lot of things everyone just seems to accept.

Washing gis constantly. Sweaty rashguards. Finger and toe issues. ears, bruises, jungle rot, black eyes etc.

What are some other things we think are normal for our sport that others might think is crazy or weird? TIA all!
