> Water Yes. I can easily fast for 4-5 days once a month with no problem. Water, I've only done it a 3-4 times in my life, just to see how I react on it. I 'imagine' (not really) the scenarion of being in some country that is frequently earthquake-struck and being without access to water because of damaged infrastructure, etc. Again, the purpose is to know one's limits and _not_ to harm oneself.

How many people live in such zones where strong earthquake are frequent, and they have the real/possible risk of being trapped under some rubble for 1-2-3 days without access to food or water? Knowing your limits and not panicking helps.

>50kg What if you got a kid and you new to carry it for some distance? What if you have to kill an animal and bring it back to chop it and eat it? Again, the purpose is to do it a couple of times in your life to know what you can and cannot do. Not ruin your spine aimlessly.
