Well thanks for the feedback guys, and yep, I've heard about the dangers of strenuous exercise early in the morning too, a workmate's brother is an undertaker and he said once that he never takes a dump before lunchtime because of all the bodies he's collected who've suffered heart attacks on the toilet, when they've strained just a little too much to "park an adder", as it were.
While the stress of a 3.5 mile walk at 5am was probably cause for concern when I was a tad over 300 pounds with blood pressure of 170/90, now I'm around 250 pounds and my BP is now around 130/70, I'm guessing it's less of a concern. I got some blood tests done a couple of weeks ago and my cholesterol is down to 4.5 too, which is great. I do want to get down to around 220 pounds, (mainly so I can wear my tailor made leather bike pants again) but that's a few months off yet.
The smoking thing is funny, I gave them away 4.75 years ago after 29 years of sticking things in my mouth and setting fire to them, and I'd love to say that I'm totally over the evil weed, but sadly, I still love the smell of cigarettes and tobacco, and often walk close to office workers who all cluster in doorways in the city (no smoking indoors here) like social outcasts, just so I can get a whiff.
Don't get me wrong, I really do love not stinking, and not seeing that yellow/brown staining on my fingers and teeth, or the "hot" feeling I always had in my chest, even after a long nights sleep, or the uncontrollable, wracking cough, the cracked lips etc, but I do love that "lit cigarette" smell, to me at least, it's as addictive as the nicotine itself.
Anyway, thanks again guys, and don't worry KK, I have some insurance in case I do unexpectantly leave my mortal coil, I've passed a large sheaf of annoying "generic" posts to my youngest son with very simple instructions to just insert these pearls of wisdom randomly with little thought of applicability or context, so he can continue with my #$%*t-stirring legacy, long after I expire..............
