>>I agree. At home I don't drink bottle water. But when I go to the gym it is easier for me just to grab a bottle. Of course, one can say that you could wash and keep refilling the same bottle. But then, they won't be able to call me lazy :).

>Actually, that's not such a good idea. Apparently the plastic begins to break down into the water after about the 3rd reuse.

I always try not to drink from plastic bottles -
for sports reusing glass ketchup bottles works quite well:
as it s glass is thicker there is less danger of breaking in the bag.
