How copious times a light of day is it mundane to own a bm?
Well, it actually vary person to character. On AVERAGE once or twice a day. In my fam, near are many different BM "routines" One personality goes every few days, another go up to 4 times in a light of day. That's perfectly majority for both of them. But each person's body is different.
One time a light of day is the usual. But you could have it up to 3 times a daytime. Alot of people shift for 3 days without one.
I would articulate one to two...
