[deleted] , living in the Los Angeles area, being middle-aged, and having had a rather active sex life over the years, I'd guesstimate that about 20% of the women I've been with have implants--and two or three women a year for the last 30 years would be a very modest estimate--so, that's a pretty good sample. That said, I'm guessing that Los Angeles is probably higher than the rest of the world.
Probably 40% or more have tattoos--but most very discretely placed. Botox, fillers, or micro-blading eyebrows? Probably 50% or more. Indeed, my daughter is a nurse who does fillers and Botox. So many people do that stuff here that she could work 6 or 7 days a week 10 hours a day if she wanted to. And there are hundreds of places that do it in Los Angeles.
