I feel that men’s mental health is that they should not feel depressed but I guess everyone is different. Some may have high testosterone or some may not or maybe some men will be sharper or some are not. But nevertheless men should have a purpose in life regardless of if it is legal or illegal but as long as you can eat, sleep and house.
Usually our needs are universal such as food and water because we need them to survive. But when we want to push further than that, we should contribute to society in order to get the luxuries we want.
In a way we all have a role to play in society regardless of what you are doing as long as it helps you stay out of trouble and eventually start a family which you should still not lose yourself in the process because women do not want to see you decline but at least growth or some consistency.
