This week's programme in the series on Man and Science today.

Only one person in every 50 people that read this will escape some form of rheumatism before their 70th birthday. Apart from the personal agony, these diseases cost the economy more in lost work than all our strikes put together, yet it's an under-funded, under-researched and little understood group of diseases.

Under the label of 'rheumatism' there are about 70 different diseases: arthritis, gout, slipped discs, lumbago, sciatica and so on. No single film could deal with all of them; what this film does is to show you what happens in some of the commoner kinds, and (where it's known) why it happens and what can be done about it. Where the answers aren't known, then the cameras went to the laboratories from which the answers will come.
