Why you would need aid now more than any other time is because if you cant get to a hospital or emergency center, the likely hood of a cut or something getting infected is elevated because of the water. The water is more likely to have germs and other nasty things in it because of sewage back up and other things. And you would certainly want to stop any bleeding before it got bad. Needless to say if your really into it, (surviving that is) store up on antibiotics and pain killers, you never know when you might be able to get to a real hospital next. So a good first aid kit is the last thing you want to have to use but as they say the first thing you’ll be glad you have!
