If you are in the sort of job where you are expected to know what was said on Newsnight, Question Time and Today, do you just not need a lot of sleep? Or these days do people often catch up on these things via online clips?
When I was a teenager I used to think that watching / hearing these programmes was part and parcel of adult professional life, but now I am guessing they are probably less important unless you are in the media or politics yourself. Elsewhere, even if it looks better if you have heard about some new proposed legislation reported that morning which is relevant to your job, it doesn't mean you have to have seen All The News.
From MN it seems that a lot of people go to bed earlier than my parents did in middle age, and earlier than a lot of my friends do, other than people who have to make a special effort to look after their health.
