As a child, my hobbies were far from eccentric. I whiled away the hours collecting coins, obsessing about Doctor Who and engaging in spirited wrestling matches with myself in the privacy of my bedroom - all perfectly legitimate for a young pup. My more peculiar fascinations - delving through the forgotten vaults of British television, hoarding vintage crisp packets, and chasing the alchemy of the perfect cup of coffee - came later, when age and money allowed for wilful indulgence.
But if Secrets Out is anything to go by, some children managed to occupy themselves with far more niche and bewildering pastimes than I could ever dream of, even as an adult.
