Grandpa hour

Grandpa hour tends to be the last hour of the day and affects men's cognitive and physical abilities. In summary, it is when men truly feel their age (and in many cases feel even older). Typically Grandpa hour sets in at around 30 years old but has been known to affect men as young as 25.
