Yesterday (and also the day before) I drank about three litres of water. And boy it felt good. My mission for February is to keep that up and develope this a daily habit. It is good for my health and my general wellbeing. I must not forget that some 60% of my body is essentially water, so sustaining this percentage seriously affects me. In the past I was drinking random quanities, ranging from ~1 litre to 2-2.5 litres. Comparing that with the past two days I can say it clearly wasn't enough. Kids, drink water. Even if you're not explicitly thirsty.
