That being said, however, there are many underlying issues that could be affecting Holt - starting with age.
Holt, I have no idea how old you are, but
Victor's mother lived with us for 7 years in her old age - 88-94. We had a space heater in her room and an electric throw for her because she was always freezing. Besides the normal thinning skin, the causes of her always being cold were that she had diabetes, was anemic, had hypothyroidism, atherosclerosis, and heart issues - all things that causes the body to lose the ability to regulate temperature.
Generally, old age - in and of itself - will cause us to lose the ability to regulate temperature somewhat, but hypothermia at 77°F is quite serious and is more than likely the result of some very serious underlying medical conditions.
Hopefully, you're seeing your Dr regularly and are discussing this with them.
And remember that hyperthermia - getting too warm - is just as dangerous.
