Off the back of the teaching bunkai with experience thread...
Given that we're all pragmatically-minded Martial Artists and people generally serious about our health, how much alcohol do we consume? At home and socially.
Personally I've been to university and done the drink-myself-into-oblivion-every-weekend thing. At the time it was fun. In hindsight it's pretty stupid. These days I drink very little. I confess to a bottle of beer on a Wednesday after my biggest class, just to chill and reflect. The exception being when I go from class to night shift. And on a rare night in at home with my other half we can make our way through a bottle of wine. But that really is my usually weekly intake. What, four units at best? This change wasn't a deliberate lifestyle choice but natural change of how I live.
What I preach to my students and that I stand by personally is that there are three things that I can (potentially) do when I'm alcohol free that are impeded or prevented by alcohol consumption:
2. Defend myself and others
3. Do first aid
All of these things can save a life.
Furthermore, with my wife's health, when we're out socially I'm usually driving anyway.
The counterpoint is that martial artists or not, we're entitled to a life and the odd pint (in the right environment and right company) is fine. The problem being when that environment or company changes. Mark B highlighted a family wedding.
So, what this comes down to is.... what effect, if any, does your Martial Arts have on your alcohol consumption?
