I think fitness men generally cherish themselves and take care of themselves. Such people will also know how to take care of the people they like, but they don't know if they are only good (selfish) to themselves. A naked head can only show that you are narcissistic and like to show off your figure; What's more, the goal of fitness is to shape a good figure, which doesn't mean anything; Reliability cannot be analyzed from this point alone. My coach is young, honest and kind to his wife, but this cannot be generalized. In fact, men don't know unless they are reliable. Sometimes it can be seen through some trivial things in life; I hope my answer is helpful to you!
