Actually do between 40 & 70 KM every day on the bike, so been trying to convince everyone that one balances the other, though nobody believes me, and that includes me...

Wow 40 and 70KM a day is a hell of a lot of miles, perhaps far too much, and the poor old ticker is trying to tell you something to not make it take the strain so much.
