From my experience.
The younger you are the more you can drink without being aware of the consequences.
When I was in my 20's I drank a 6 pack of beer a day.
In my thirtys I slowed down to a 6 pack in 2 days.
In my 40's I was down to 2 beers a day.
In my 50's a six pack on the weekend.
Still holding to a six pack on the weekend in my 60's
I tried to drink everyday when I retired 3 to 6 beers a day.
But I couldnt handle it.
What I mean by I couldnt handle it is I can not process the empty calories out of my system fast enough.
Therefore my Blood pressure, weight, colesterol and blood sugar goes up.
That is a deadly combination leading to any number of dire consequences.
Also my body hurt. I could not play soccer because my knees and legs hurt.
I curtailed my drinking to a 6 pack on the weekend, my wife thinks I am only drinking 3 beers on the weekend,
no meat before dinner, little red meat mostly chicken, fish and vegetables.
And I am running like a banshee.
Playing soccer 4 nights a week. Succussfully defending and keeping up with 20 year olds.
4 90 minute games no breaks.
I realize i drink when I am bored and have nothing to do.
Soccer entertains me, gives me something to do.
On days when the games are rained out, I end up in the beer.
Thankfully it only happens about once every 2 weeks.
I will have a problem when i get to old for soccer.
The oldest person I play with now is 74.
With him as my role model I should have 12 more years
then I might go back to the bottle and die a drunk
unless I find a replacement.
My other passion is music.
But music is played in bars.
If you hang around in a barbershop long enough you get a haircut
and if you live and work in a bar you will drink.
I have already conducted that experiment on myself.
That is my experience
Results may vary.
