A father-of-two who was scared of heights has become a daredevil who skydives and abseils after having his adrenalin gland removed left him with no fear.
Jordy Cernik, 42, has dived out of a plane from 17,000 feet, abseiled down a 418ft tower and zip wired across the Tyne Bridge in Newcastle.
Heights - Operation - Adrenalin - Body - Flight
But he was terrified of heights until an operation left him unable to produce adrenalin, which gives the body a 'fight or flight' boost in dangerous situations.
Mr Cernik suffers from ultra-rare Cushing's syndrome which causes high levels of the hormone Cortisol - a steroid that regulates the metabolism and immune system.
Years - Territorial - Army - Recruit - Mr
In just three years, former Territorial Army recruit Mr Cernik, who is 5ft 8in tall, ballooned from 11st 5lb to almost 17st.
To treat the condition, Mr Cernik underwent a series of brain operations and two procedures to remove his adrenal glands, which also produce adrenalin.
Trip - Disneyland - Side-affect
But it wasn't until a trip to Disneyland in 2012, when the unexpected side-affect was revealed.
Mr Cernik, who was scared of heights, decided to sit on a rollercoaster that would have terrified him before and realised that he felt nothing.
Fluke - Years - Plane - Tower - Fear
At first he thought it was a fluke but in the years since he has dived out of a plane at 17,000ft and abseiled down a 418ft tower and felt no fear.
Even as he dangled his legs over the edge of the Tyne Bridge - 84ft above the water - before sliding down a zip wire to the Gateshead side, he did not feel scared.
