Kevin claims he is 70 years old!

In his second book he makes this claim. How ridiculous! He says that though he looks like someone in his 40s he is actually 70 or a figure close to that, I forget the exact age. How can he go about lying like that? It makes you wonder how much of the stuff he is saying is true... like the fact that he claims to have been a secret government operative for 20 years.
