Other Members want to contribute to the debate, so I will not give way to the hon. Gentleman. He might have an opportunity to speak later.
If we are to change the retirement age for the careers in question, we must undertake those physical tests as well. My hon. Friend the Member for Finchley and Golders Green (Mike Freer), who is of a similar age to me, has said that he is going to do the police test, and I have agreed that I will do the firefighter test. I reiterate his challenge to the shadow Minister and to the Minister, both of whom are at least a decade younger than us, to sign up to do those tests if we are to proceed with the Bill at the end of Third Reading. I would be very grateful to hear them accept that challenge, and indeed to hear the Government Whip, the hon. Member for Chelsea and Fulham (Greg Hands), do so.
