Why are so many US politicians so old?

This week two key figures in US politics are generating headlines, in no small way, because of their age.

Yesterday, House Speaker Nancy Pelosi announced her plans to step down as leader of the Democrats in the House.

At 82, Pelosi said the hour has come for a new generation to lead.

However, she will keep her seat and Congress with no plans to retire.
