I have often thought the same thing. If I have a fraction of the energy and strength of will that Bernie (74), Hildabeast (68) and Donald (69) display when I get that age, I will be impressed and surprised. These candidates have not really had a full week off in months!!!
D Trump is a work-a-holic. So they say. He gets little sleep and is up very early.
Gonna be a very rude awakening for the staff at the White House when he arrives. Its 9 or ten now, then switch to four or five in the morn for the new POTUS?
Coffee will be a very valuable drink around there if Trump allows it.
