Drinking– How Much is Enough?

According to an article in the British Medical Journal by Glasgow physician Margaret McCartney, MD, not as much as we think. Dr. McCartney is on a campaign against Danone, the makers of Volvic and Evian, who appear to be more interested in profit than health. She alleges that there is no need to force oneself to drink more than one might desire and that it is unnecessary to carry a bottle of water with us wherever we go.

Interestingly, the idea that we should drink eight glasses of water per day rather than just obeying our thirst is catching on, not just in places where high temperatures make drinking enough advisable, but also in Scotland, where very few people are overcome by heat. Is it necessary? It would seem that Dr. McCartney, for one, does not think so.
