Mark Mair’s family never thought he’d walk again after his accident, let alone invent a new tool.

In November 2011 the 29-year-old from Stevenage was travelling along the motorway near Sheffield with two friends after a night out in the city when the car in which he was a passenger was involved in an horrific smash involving two giant juggernauts.

All three people in the car suffered serious injuries and Mark spent two months in a coma.

“I can’t remember anything about the crash,” he said.

“I woke up in a hospital bed in Sheffield two months later with my family around me.

“In the time I’d been asleep I’d lost 91/2 stone and grown 21/2 inches.

“After waking up I had to learn to walk again and used to have to crawl everywhere. I was also incontinent so had to learn to use the toilet again.

“It was like being a child. It was really tough but I’ve come through it now and it’s made me realise how lucky I am to be alive.”

Mark used to be a professional bodybuilder and says he was a really angry and ignorant young man before the crash.

“The accident changed me for the better,” said the former carpenter.

“I’ve always been religious but since my crash I’ve become even more so. It helped me see where I was going with my life and what I wanted to do.

“I’m not angry anymore and can channel my energies into doing good things instead.”

Since recovering, Mark has focused his energy on finishing a new tool called Doorpod which he began designing before the crash.

It is made to help unskilled people hang doors easily or speed up tradesmen in their work.

“I was a carpenter and want my invention to help people do things they wouldn’t otherwise be able to do.

“It hasn’t been easy building and designing it especially after everything that’s happened to me but now it’s finished I feel mentally stronger than I ever have.”

Mark now plans on taking his invention to trade fairs and shops around the country. He will use any money he raises to build a house and provide for his two-year-old son called Luxxe.

“My family are everything to me and I want to always be there for them,” he added.

“My life hasn’t been easy and I’ve made lots of mistakes but I feel now that I’m turning a corner and things are getting better.

“I know I have a great product here that can help a lot of people.

“My next challenge is to get it out there and convince people that it works and show them how it can benefit them.”
