A pensioner has gone viral with a nifty invention he created to help people with limited mobility put on clothes. Bob Scott, 76 who suffers with Parkinson's, came up with the idea of 'Bob's Flunkey' when he pulled a muscle while pushing his friend's wheelchair. The Flunkey’, involves him tying a piece of string to a bulldog clip which is then clamped to a door so he can put the clothing on at his height. It means he doesn't have to raise his injured arm above shoulder level and can help anyone in pain or suffers from limited mobility or disease.
