BBC Documentary

I can't for the life of me find/remember what that BBC documentary was called where they've been following the lives of a couple of people from when they were 7 years old. I think it's been going since the 70's and they check up on them every 7 years or something. I'm not entirely sure.

Any ideas what the name of the program is?

Cheers!

The first one was called Seven Up! And it was made in 1964. The last one was broadcast in 2005 and was called 49 up. I think there was an American and a Russian version as well.
