Obviously, no mere mortal could keep in top physical shape for that long - the man would have to be about 80 years old now. So what is his secret?
Is there more than one man behind the agent - is the name "James Bond" also just a codename? This would explain the different faces, the regular ageing/de-ageing that occurs on face changes, and also the fact that the man is constantly loyal to the same job and country, with no signs of tiredness, weakness or lack of determination. Still, the agent chosen to take on the role of James would need to be exceptional - he has to learn a new persona, family background, and style of being. All reference to his own family and past must disappear to be replaced by the James character.
A third theory was suggested to me after someone read this - maybe he's a Timelord (a Gallifrean, the same race as Doctor Who)?! This would explain the regeneration with a different face. However, I think that the double heart may have been noticed on his trip to a public health farm, although I'm sure the agency doctors would be clued in on his abnormalities. This requires further investigation...
That's what everyone else has on their JB pages, so someone tell me if I've got it wrong, OK?
