I was 68 a couple of weeks ago and can still do a full day's graft no problem.
I smoke too much, drink too much and weigh in at 17 stone. If I can get my hand to it I can pull myself over it, but it's getting harder. I get up at 6.15 and go to bed at midnight and that's my problem, I'm just not getting enough sleep.
I have had to pull over for a 15 minute kip when less than 5 miles from home, and I often get in, see to my water and battery, have a shower and get my head down for an hour.
If I push it too hard one day to get an estate finished, I will be drained on the next day by 3pm.
I just need to pace myself a little better, If I could get myself to bed by 10.30 I could fly through the next day, but I just don't do it. It's my own fault if I get knackered. Having a wife in her thirties, and a seven month old baby doesn't help with the sleep deprivation either.
One of these days I will fall from under my poll, but I will only have fallen asleep on ther job. Dai
