Yes, this is dangerous, and he should cut down at once. The government is quite right in telling us what the limits are. They are 21 units a week for men, and 14 for women, that is units, not pints. Governments are supposed to protect people, and if they did not do that they would not be doing their job. As for pub profits, stuff that, people's health is more important than those. You can get leaflets about this matter, which I would get if I were you. I have had 2 friends both die of alcohol abuse, one at 39, and one at the age of 56, so feel strongly about this emotive issue.
