Lord Winston (Lab)

My Lords, I must declare a conflict of interest in this respect, because I am not quite certain—I have rather forgotten—but I think my 85th birthday is next weekend. I have to say that I am still employed; I am still producing experimental work, which is being published; I am still teaching; I am still training post-doctoral students and younger students; and I am still talking to children’s schools. The fact is that we are discussing a biological problem, which your Lordships seem to have neglected. If we had a rule that we only had people of a certain height in this Chamber and that, let us say, less than 5 foot 10 would not be acceptable, we would actually forget the Gaussian curve of normality and the statistics. The fact of the matter is that, if we look historically, in the last 20 or 30 years of this House of Lords there were many people in this Chamber who were actually demented in their 60s, and far more in their 70s and 80s who were actually clearly not suitable mentally to be taking judgment on legal issues and issues of social care. The fact of the matter remains that medicine is changing, and there is no doubt, if we actually get successful medicines in future, as we in the Labour Party hope—we will have to see about that, of course—that we will see ages increase and people being mentally competent for longer. I suggest that an arbitrary rule at any age is probably inappropriate biologically, and we should find a more sensible way of considering how we might encourage people to retire when they are no longer competent to be Members of this House.
