I just gonna remind you one thing, but srsly how does doing this help the ones that have that disease. Not to mention, look how much water is wasted in that challenge, imagine all the world wasting this water, for what? To feel them? Why do you need to do this, in order to help them or "feel" them? The tons of clean water that's beeing wasted just reminds me this:
Look it doesn't mean america alone, but kinda those which are doing it. Not trying to destroy the fun that some have by doing this, but let's not forget about the people which are still around without clean water. I'm sure the once having the disease, if they care for others too, they'd say the same. I'm not taking this desease lightly or anything, just want to remind what it is to be aware of things, think again.
