For example, I only feel like myself when I'm regularly boxing (competitive, high volume anaerobic+aerobic, physically intense), spending time alone and outside, adhering to a higher fat diet/lower carb diet, occasionally blowing off work to do something else, and so on.
What I take from this is that men respond well to testosterone. There are a number of testosterone boosting activities and foods that might help, including acute treatment when necessary. Glad this is getting recognition.
