I'd say the best thing about aging is that most men don't do it well. So if you are one of the minority of men who stays fit and healthy and takes care of their appearance then you can do very well with women slightly younger than you. And women are also aging better than they used to so there are some good pickings in the 35-45 age range and men can date in this range into their 50s. Although even then you can't get by just on looks you will also need money and status as women at this age want comfort.
Yes, just keep lean and look after yourself. Weight training and good diet for male hormones. Hair transplants help if you can afford them, and are much cheaper in countries like Turkey, Bulgaria, Azerbaijan than here in the UK. I'm a darts fan and I just seen an older player who's now 56, looks like he shed a ton of weight and grew a good beard. (last time I saw him was in 2002 when he was fat & bloated jelly baby). Looks better than he used to.
Yes same guy in video as the pic.
