In today's technological age - is heavy manual labour disappearing or is it just becoming invisible?

Physical work was once celebrated with hymns of praise. But workers today must be content with encouraging one another that their hard work is better than no work at all.

This series looks at the state of physical work in today's world. Work that is dreary, demanding and at time dangerous.

Lions

We take a glimpse inside the bloody and frenetic activity of the Port Harcourt meat market in Nigeria. Here cows and goats are brought to the slaughter - then cut, roasted and cleaned for sale.

The slaughter yard offers a hellish vision of noise, blood and smoke - viewers may find some scenes distressing.
