Keith Richards and Mick Jagger are probably the gold standard on aging rock and punk stars and shirts. I don’t think Iggy has any more wrinkles than Richard, nor more belly fat than Jagger. If they’re good then he’s probably good, too.
Not sure I agree about the hard liquor part. I think the worst of it comes from the sun. Iggy’s not that much older than me. Back in the day nobody thought twice about a bad sunburn. You peeled but then you tanned up. Taking multiple sunburns wreaks total havoc later in life, though.
Drinking wouldn’t help, that’s for sure. But based on my experience I think the sun accounts for the worst of her appearance now.
Top of my shoulders looks like Goldie’s shoulders now. I remember spending many days oceanside while wearing zero sunscreen. In fact, I don’t think sunscreen existed in the 1960s and 70s. Most people applied baby oil because it was cheap. Baby oil also amplified the sun’s effects. I have had many sunburns where the skin on my shoulders blistered up. Not unusual.
I have that skin checked regularly for skin cancer now. I remember a nurse gasping at the damage, and this was twenty years ago.
