I do drink 2L/day. Guess what my environment is ?? <img src="/images/graemlins/grin.gif" alt="" />

Last summer, during a hot day, I drank 3 and a half liter, while walking 4 to 5 hours.
Adding what I drank after that, in the evening, I must have drunk 4.5 to 5 liters at least that day. That is a record for me !
