gnu, I wonder why some people can take drink and then leave it, but others go on and on, seemingly unable to stop? For instance, I thoroughly enjoyed a half of Adnam's bitter when younger, but never ever got drunk. But others would have pint after pint, week in and week out. Some of those may have gone on to become alcoholic. Why the difference? Is it just a personality weaknesss, lack of self-control, or a genetic disposition to addictive behaviours?
Why do folk keep on 'pouring fat into their jeans', while others know when to stop? This to me is the mystery.
