A person that drinks enough can have health problems at age 25 the same as that of someone who is 50. Alcohol is prgressive in the damage it does as well as the addictive properties of drinking it.
A friend was sharing how his Dr put it when he stopped...
(Friend)Now that I stopped, I seem to be sick all the time.
(Dr) Now that you stopped, you are seeing how sick you were while drinking.
Your not remembering
Lots of weird situations occur due to my drinking -- or everyone's drinking. I do notice weird things have occurred while I was drinking and some I can barely remember and of course some i totally remember.
Age brings it's own heath issues and adding alcohol can bring other issues as well. Sober, we see them all and can get treatment faster, as needed. Sober is healthier.
