Alex Trebek did live with his mother but in his own home.
Alex Trebek did not live in his mothers house nor was he mooching off of her.
At least this is what I remember a few years or so ago.
I believe I heard Alex Trebek say on some Talk Show or something that he did Live with His mother to help care for her.
But he lived in his own house but his mother actually lived with him.
There's nothing wrong with family living together in the same house no matter what the age.
Sadly Alex Trebek died yesterday on November 8th 2020 at his home and was 80 years old.
Alex Trebek died of Pancreatic Cancer which he had been diagnosed with a few years ago.
