Shave and a haircut, two bits.

For 17 years, 37-year-old Lenny White was a marketing consultant for the Yellow Pages. Then he decided to change his job and "do something more worthwhile." In June, 2016, he got a diploma in barbering. He set up a mobile barber shop which he takes on the road to nursing homes across Ireland. His specialty? Elderly men with dementia.

He finds that everything from the lemon-scented cologne to the light-hearted conversation makes the men feel young again. He uses an old juke box to play songs by Dean Martin and Frank Sinatra that they heard when they were young. After the music started, White says "we instantly saw a massive difference and knew we were on to something. Men who were previously agitated would relax, sing along with the music, and tap away to its beat. I'm really excited as I know these men are not only going to look better, but also feel better."
