I have an in-law with a similar issue, not just sleeping but just so lacking in energy and motivation.
I personally see a 30+ year habit of poor diet, no/minimal exercise, huge screen time, lack of nature and fresh air, poor sleep pattern and amount and more. Add in real key issues such as regular and binging on alcohol, occasional weed smoking and excess and binging on processed food and it is a recipe for ill-health.
It has culminated in a real sloth like approach to life, and one hard to break out of.
That's my DH to a T, apart from the weed smoking. He doesn't drink a lot of booze either. The rest is him though. Never goes out for a walk outside, zero exercise, never gets fresh air, doesn't lift a finger in the house, eats crap, (processed food, sugar, fat, and carbs,) and sleeps FAR too much. He is also on the computer or in front of the TV for much of his waking hours, and is some 4 to 5 stone overweight.
He said he doesn't have time to go for walks, or do any sport or exercise. A lie. He only works 3 days a week - 27 hours, and as I said, he does nothing when he is not working. I do everything, and also walk every day (3 miles,) and go swimming, and play badminton. I also do all the housework and cleaning and shopping etc.
I see him dying before he is 70. (Currently mid 50s.)
Being very lazy and sedentary is NOT a good way to live. It is NOT a healthy way to live either.
