Re: A warning. Please read.
It is quite incredible the stuff they do day on day these days. I've had three angioplastys, five stents in total, and the last two were in and out the same day. Even with a bypass I was in on Monday evening, under the knife Tuesday and out on Thursday. Simple stuff for them.
I was talking to a fellow dog walker, an elderly lady, the other day; her late husband was one of the first in the UK to have a heart and lung transplant, about 30 years ago. He was expected to last 6 months or so but lived a further 10 years. He was an ex Sergeant Major who kept himself fit, which helped.
Fit or not, you can't change your genes and even a slightly crap diet can tip you the wrong way, as in my case.
Did they tell you what you'd done to deserve it HM?
