Boris is 60 and though presumably pretty healthy and wealthy doesn't being 80 when your child is going to be at uni cause challwnges? I always think with these things you are risking a child becoming a care fiver at an early age or having a distorted view of a parent due to a large age gap.
The older Dad option also seems to the option for famous and wealthy men and personally I do not know many women in their bid 30s dating men who by some measures are pensioners.
Good luck to them though
