A shirt can work as a sling in an emergency
Nobody wants to get hurt, but unfortunately, there is a possibility that it might happen. So, it’s important to always be prepared for any eventuality by learning how to make a sling from something as widely available as a t-shirt.
This trick only works for arm injuries. Pass your head through the top hole, then put your injured arm through the shirt’s opposite armhole. Adjust it as necessary to ensure that it is comfortable and keeps the injured limb close.
