Drinkers 'ignorant' about alcohol

Three-quarters of drinkers do not know a typical glass of wine contains three units of alcohol, a survey for the Department of Health suggests.

And how many commentators including the fellow who wrote these reams know what a ‘unit’ actually is? I don’t know and I don’t care but these people are taking it seriously so might be expected to know of what they are talking.
