Why ??
When I no longer enjoy what I do, or the body won't let me, that will be the time.
Maybe, I think.
I would still like to do a bit of part time until a couple of days before I fall of my perch.
I have a morbid fear of living the life of a lounge lizard, watching re-runs of Days of our life & I love Lucy, until the remote control is prised from my dead fingers due to a massive coronary occlusion.
Cheers,
Shorty..
Always looking on the bright side of life ;-)
