And this is counterproductive, in my opinion. If medical associations and health ministries set such unrealistic bandings of what is 'safe' and 'unsafe', the danger is that most people will fail to adhere to the limit, and then feel 'in for a penny, in for a pound', and not try to regulate consumption of food, salt, alcohol beyond that threshold.

'I've already failed - it makes no difference now. Finishing second in the race is the same as finishing fifty-seventh.'
