It seems that grappling is the safest way to get your body used to reacting in a composed manner under a high adrenaline situation. Let's say for example it took someone three months to get used to operating with an adrenaline dump through grappling twice a week. What about something like bouncing at a bar? Since less time is generally spent in fights at a bar would the learning to be composed in those situations take years while grappling would only take months? How long did it take for you on the mat? Any general thoughts or perspectives welcome.
