I don't know how people function normally drinking some of the amounts discussed here can only imagine they have forgotten what normal feels like.
Or they aren't you, and have different tolerances/capacity's. Not everyone is built the same way, and people handle alcohol differently.
read an article recently that suggested the threshold for properly dangerous drinking was actually MORE than a bottle of wine per night. I know it flies in the face of all other medical advice but I do wonder if there's something to it.
I've read a few studies recently, one suggest that for some only 10 units a week will cause long term problems while for others problems don't appear until over 60 units a week are consumed.
A more recent study said that 5 hours of moderate exercise reduce even heavy drinkers dangers of long term problems to those of a teetotaller.
Another looked at the fact that most people who develop lifestyle diseases do so because they are committing several health sins, they drink too much, smoke, are obese and don't exercise. It's the combination that causes issues, whereas if you limit it to one "sin" you will generally be pretty healthy.
Recommendations are just that, recommendations, not laws. We all have our vices, it's just a matter of whether or not it takes over your life.
