Could you imagine entering a reality TV competition at the age most people are enjoying retirement? Jerry Macdonald did just that, and his stint on "Big Brother 10" became legendary.

In the summer of 2008, when the tenth season of the American reality television show "Big Brother" premiered, viewers were instantly captivated. Among the thirteen houseguests vying for the grand prize was Jerry Macdonald, a 75-year-old retired marketing executive. His participation was more than just a casting choice; it was a statement. He wasn't just the oldest contestant that season; he remains the oldest contestant in the show's entire history (US version). "Big Brother 10 (US)" stood out as a season that focused on strategic and social gameplay, moving away from excessive twists and turns, and Jerry's presence fit perfectly into this dynamic.
