I have had a similar experience. Lost 40 lbs, and discovered that decades of weight lifting really had paid off. I also had a couple of moles removed from my face. Neither was for cosmetic reasons. (Actually, I guess the moles were. I went to a dermatologist for a skin cancer check as one should when over the age of 50, and asked if he could remove them while I was there. It took less than 10 minutes.)
I had a ton of work experience before this happened, but now people solicit my opinion. I also landed a new job that pays a lot more.
I won’t go so far as to say that women fawn over me, but I find them to be as friendly and chatty as most men are now. (I’m happily married, so I don’t go out of my way to flirt.)
Overall, I probably went from a 4 to a 6, but it’s enough to notice a difference.
I had one at 46, and 12 years later I’m glad we did. That said, it is draining to keep up with him. I had to get my physical fitness shit together, and that helps. I also aim for 8h of sleep per night. (I didn’t get that with a newborn, but I do now.)
