To disqualify the performance of a man only because he has certain signs of old age is a controversial issue.
I can quote the performance of Sir Winston Churchill, (1874-1965). He was PM until 1955 (81 years old) and MP until 1964. Other example is Giuseppe Verdi, the
famous Italian composer, born in 1813 and died in 1901, who in 1893 (80 years old) was able to compose Falstaff, an outstanding opera.
I see that there is now a glorification of youth, but things sometimes have exceptions.
Joking aside...we all know they're just figureheads. The 'real' decisions are made by others.
