hey i was just thinking, i dont know if my idea would be good or not but ill tell you guise. :D 3 words "pee and poop!" now i know what your thinking EWWWW! BUT we all are always eating(beans) and drinking where does it all go? There could be a bladder meter just like the food and water. and you could take dumps and if you dont cover it up it could attract zombies! and if you need to take a Piss you better get out of the city because the sound of urine hitting the dry grass is loud! if you have an empty water bottle no worrys pee in there and let it sit in the sun a while BAM FRESH WATER URETHRA (bear grylls). :D well thats it tell me what you think, Or you can even add on. OR tell me how pointless this is!;)
