The Geezer is not against naps for seniors on principal. Especially as the weather warms up, a sloggy feeling midafternoon is inevitable. A siesta makes sense. If your body is telling you it would like to briefly shut down, do it. It is always healthier to obey your metabolism. Forget the self-esteem issues over what people with think if you snore quietly for a few moments. Who cares if they look at you as if you deep into your second childhood?
However if sleep is already a concern and getting a decent 4 solid hours is difficult and the bottle of ambien on the nightstand beckons, I’d avoid naps. They will further mess up your already messed up sleep patterns.
I may be wrong. The Geezer admits he never attended medical school and squeaked through Chemistry.
