“Doing that for a while, the general pressure of work and home built up,” he said.
He woke up about 4am one day with tingling in his arm and he doesn't remember what happened after he got up.
Fortunately his daughter was visiting that night. She heard banging, which turned out to be Harrison having a spasm on the ground, and she called an ambulance.
Doctors found a benign brain tumour and they had to cut right across his head to remove it. He needed 27 staples to close the wound.
“It was a big wake-up call.”
He was medically discharged from the army and now is the full-time carer for his wife.
