Medicare fraud. They go to your house to see what kinds of medical devices and hardware they can bill for. Think scooters, ramps, stair chairs, maybe even an elevator "so a wheelchair can fit on it". They may not even tell you about it - they can bill Medicare for stuff they "buy" for you and if you don't know about it nobody is the wiser.

When my wife (who is 2 years older than me) is finally eligible for Medicare sometime in the later 2030s and they try to pull that, all my cameras will be recording into Zoneminder with full audio. I may even be able to hide them by then. I plan on being the classic old guy shaking his fist and yelling "get off my lawn", and I can't wait to go scorched earth on these a-holes. I hate it when seniors get taken advantage of, and I plan on doing my part to help stop it.
