She talked about it on stream a month or 2 ago, about she thought she woulda been done at 35 and she knows she doesn't have much time left in that area so it's def something she has thought about more recently.
There is/was an old RT Couples video Geoff and Griffon hosting (prior to their divorce) where Meg explicitly states that she knows that her work has a "shelf life" and this was before she pulled out the titties.
You don't see old Porn Stars out there still working, not without a MASSIVE fan base and/or lots of plastic surgery.
Meg has neither of these. And before you get your panties in a bunch, Yes Meg has a "large" fan base, but that's:
1) shrinking
2) no where near the size of some retired porn stars like Gianna Michaels or Madison Ivy.
And yes, Meg does not do porn. But she DOES sell her naked body, which is close enough for the normies.
