The piece makes a case that it is not about obesity but about a variety of medical conditions that promote the growth of breast tissue. Maybe. However, there are a lot of guys who are developing fat chests rather than breast tissue or what we used to call bitch tits.
When I was fatter I used to have a fat chest and as a teenager I was made fun of in the changing room for having "tits". It was fat though. As I've leaned out over the years, I've lost them.
Surgery is maybe too easy a way out. Yes there are those with medical conditions that require surgery, but maybe others could do with simple fat loss?
