Just wondering whether its worth further checking ones health, over and above that of a normal Class One Medical examination?
IMHO yes it is, and I'd certainly recommend taking advantage of any screening your GP or local NHS recommend/offer....OTOH I'd be aware that there's no doubt a profit motive behind some of the advertising you see on the TV etc for whole body checks etc.
or other such scan?
One for the medics, I think the theory is MRIs are fairly harmless but I'd avoid CAT scans unless there's a darned good reason.
I've got to dash out right now but I have some experience of all this so later on I'll also PM you on the subject...
