I'm towards the upper end of the 40-60 age range.
Had I not made a really bad life decision 13 years ago, I'd be looking for a Ferrari now, but getting rid of an awful wife made more sense, costly though it was.
I manned up and visited a dentist recently for the first time in 20 years and after two scale and polish sessions with a very lovely hygienist, my smile is now almost like Rylan's. I don't think my arse would benefit from a lift to be honest so it's probably best left as it is.
Am I happy? Yes, mostly. I'm playing with a very successful local band and the buzz of playing festivals is amazing. Coming home after a day at work knowing that the evening ahead isn't going to be spent arguing about something trivial is great, because there's nobody here to argue with. Since becoming single, many of the friends I lost because of my toxic soon-to-be ex-wife have welcomed me back into their social circles. I've compiled a Bucket List and am slowly but surely getting through it. I can feel lonely occasionally but on balance, life's good.
