Nobody on this planet can live without drinking water. I'm a researcher in the field of drinking water at the Amsterdam Water suplly. In my free time I play flamenco guitar, do some jogging and rowing and visit my friends and family.
Life exist almost everywhere. Even at 10 km deep at the bottom of the ocean with high pressure and extreme temperatures.
Our knowledge is "a dot at a line". If we can find life do we know how to interpreted it?
