BRAINSTORM

Social historian Donal Fallon (left) presents the series that seeks to answer a range of compelling and intriguing questions.

So far, we’ve had fascinating and surprising answers on everything from hurling to hangovers and pollen to postcodes. The third instalment asks whether 10,000 really is the magic number for steps in a day? What does communion tell us about society? How did we deal with a housing crisis in the past? And what is rhythm? Donal also finds out if dogs can bring emotional benefits to their owners. Monday, 7pm, RTE One
