A friend of mine in the psychiatric field said that More than 5 tats was the sign of a sociopathic personality.

The “internetainers” Rhett & Link have an anti-tatoo vid where several grossly overtatted & overpierced humanoids warn against the folly of integument inking.
One of them observes, “After all, doesn’t your body already have enough holes?”
FWIW, the first body tatooing I ever heard of was an opera diva who had her name and SSN tatooed on her abdomen, declaring, “Nobody will see it except my husband and my doctor.” She had a fear of flying and an acute fear of transatlantic flight. Final ID, you know.
