I was dehydrating, could not find anything to drink in the area I was in... all of a sudden, it starts to rain. "Thank God", I thought to myself... "I am saved"! Looking up to the sky, I tried to catch the raindrops with my mouth. But alas, I could not drink it. Don't you think it would add to the feeling of realism if this was possible? Obviously, it would not be as effective and a lot more dangerous than drinking a soda can... but still, a slow replenishing of the liquid indicator would be nice.
