Later that day, after the children were back from school, he decided to have a shower and as he walked into the shower the symptoms hit him.
“I felt like I had stood up too fast and suddenly felt unwell.
"I turned around, still in my towel, and said I was going to sleep a little until the feeling passed. I collapsed on the bed, still in my towel, and that is the last thing I remember.”
He said he was not generally one to sleep during the day, but nobody in the house thought it was particularly noteworthy.
