Strippers and leaving the profession

As someone who has been in strip clubs several hundred times and who has had multiple regulars, I have seen the biggest early career ender being excessive weight gain. Number two would be a drug problem. Is that what you have seen? While some customers go for the heavier strippers, most prefer more slender ones. I ran into an old favorite from Harem House in Indianapolis at Dancers on the other side of town recently and she said many customers now tell her she is too big for them and it is hurting her income. I would guess she has added thirty to forty pounds. How much weight gain is too much? Also, have you seen strippers get back down to a normal weight again and extend their career?
