A former coworker was previously employed in high finance in London, his entire job was keeping the rickety lattice of interlinked spreadsheets across the company working and alive. People would type in a number in one spreadsheet, and after several hours, another number would appear via the lattice in a more influential spreadsheet.

The company made money, so it worked, but he swears is caused him to start prematurely balding. Maybe a convenient excuse, but also plausible.
