So now I am 50 and someone asked how I felt: Oh about 50-50?
 
No seriously - I feel I am now in the real grey haired brigade - I should relax - be a sage advisor. But I can stop being full of enthusiasm and life for the work I do.
 
I just hope it doesn't change me.
 
I pleased that at least I am old enough to see Meryl Streep in "Thatcher" - because it is not suitable for minors.
