Good Luck Trevor, I had a heart attack in 2005 and they fitted a stent, since then no problem so don't despair.
If you happen to read this remember the Spurs fans from the Terminus pub football team who you gave tickets to to see Forest v Spurs when Spurs won 0-3 and took away your unbeaten home record?
We also returned to Plymouth in an estate car with a dishwasher/tumble-dryer?? which you had bought for your mum as a gift. You made a great effort for us to have a super day and introduced us to both sets of players.
Still a great memory and I will always be grateful for that day,
Get well mate.
