I go through phases in watching This Old House...
For a show that's been around 40 years, they are relatively healthy people.
The deaths:
•Russell Morash, the executive producer - 88
•Roger Cook, after a long illness - 70
•One of the Ferrante Brothers (tile guys) literally died on one of the days they were recording. On that final day, Joe did not look good and the job he was doing wasn't very good. Heart attack - 56
•One of the kids in their apprentice program, GenNext, died of a pre-existing medical condition. - 18
Not bad for a show around as long as it's been. Of course these guys work and stay active as opposed to having a lot of free time to screw around. Plus, they were a PBS show. Different type of workplace.
