I recently had a nasty fall that required me to dress and change my bandages everyday. The kind of wound that I had was quite deep and wide, and bang on the knee. Imagine, for almost two months that it took to heal, I had to use two set of ointments, one cream, sterile gauze and tape, to hold things together. It was painful and a long-drawn process. If only I had access to concepts like the Popband-aid, those two months would have been easy for me.
