He has acted those parts, he shares a similar life story to Annabel Croft, in an interview with Michael Parkinson Annabel Croft said that the most improtant thing for success life is speaking politely and confidently socially and in public, doesn't sound much does it? yet who is Annabel Croft, she played competitive tennis once, did she win? no idea, yet Google female tennis player on tv and she pops up, now look at Nigel Havers, a second rate actor, perhaps I'm being unfair but hardly an A lister, what is his skill set? being charming and?..speaking politely and confidently socially, anything else? nope that just about covers it, handsome to the mature lady perhaps, that's about it, he, and Annabel Croft have carved very sucessful careers out of nothing but speaking politely and confidently, they are examples of a Great British tradition, household names that didn't actually do anything and we didn't notice, personal success based on nothing more than being able to speak well, smile at the right time, and be thoroughly charming.
That is a life lesson for young people if ever there was one.
