I'm currently working on another post as soon as I am done sending a pm to Penguin about some things I am looking to clarify for his roleplay so I can finish a sheet.
Now to continue with information needed to survive the apocalypse. When looking for medical supplies most people will take simple things like Neosporin, bandaids, bandage wraps, peroxide, first aid tape, pain pills, and so on and so forth. What is left behind is prescription medicines, maybe some gauze pads, self-adhering wraps, and pain relief ointments. What you don't want to do is collect the prescription meds. Prescription medicines might be a good idea short term but unless you have a medical professional with your group you don't want to takes pills just according to what you feel is fitting. Prescriptions can be highly addicting and what you don't want to deal with in the apocalypse is an addiction to a drug which has gone out of production. What you need will be the pain relief ointments, specifically the kind for joint pain. This way you can relieve the pain you endure from intense physical work everyday in your group.
If you find an unopened box of gauze pads or gauze wrap then take it. Gauze in general is a good idea to have as it is a sterile bandage that is very easy to use and very flexible. You don't want bandaids to cover large wounds on your body since they restrict the flow of air which hinders the coagulation of blood. To go on a short spiel here, oxygen sticks to blood causing it to turn red but also changes the density of blood allowing it coagulate better. Self-adhering wraps are mostly for covering over the gauze but some have bandaged sides so it can be used as a bandage. You want to pick up things for long term survival as well. These include fiber supplements, diarrhea relief, various vitamins and supplements, cold and flu medicine, and cough drops. If there is a person who smokes in your group, get nicotine and wean them off smoking so that they don't hinder the group.
That is all I'll give y'all today. Perhaps at one point I'll open a guide in the Articles and Guide forum about surviving an apocalypse at this rate. What do y'all think?
