Whereas personally, I'm not that bothered about water. If a jug is sitting in front of me in a training course, I'll put away a couple of litres every couple of hours (and sprint to the loo at every break), but unless someone puts it in my hand, I'd rather have a coffee. Not a million coffees all day and night, and also I don't really drink tea very often at all. But if I'm thirsty at home I'd rather go for milk or OJ....
