What we used to do all night, takes us all night to do!"
>>What do some of the old people say...?<<
Well, my wife and I both turned 54 and I would not be a gentleman to answer the quiestion directly. I will say this: That kind of intimacy (daily sex) both solidifies an already strong relationship and effectively reduces the significance of “less than perfect” other parts of the relationship.
And spouses who have sex “every day” are much less likely to stray, for logistical reasons if no other. ;)
