On my way into work yesterday I had a heart attack on my 06 Triumph Tiger, blacked out while doing around 50, somehow missed all of the traffic, went through a corn field and woke up when the bike hit some ruts and was throwing me on my head.
Other than that, an uneventful commute.
Contrary to popular belief, heart attacks can go on for a REALLY LONG TIME!
Have stint in aorta which was 100% blocked, have really strange heart rhythms and am told this is the worst type (of course), blood pressure drops to Night Of The Living Dead Level and bike needs at least lights and windscreen.
I can't think of any particular words of wisdom other than to try and avoid getting old if at all possible.
