I used to sleep about 5 hours a night well into my 50s, but then started to get respiratory infections, especially brought on by plane travel. After many years, my sleep habits were examined and I was told to get at least 8 or more hours a night. This is hard, so I usually make up with an afternoon map. This has cured the infections but has cut down the number of active hours each day.
