They are but they are not by default. I've seen old people that cant control their emotions. 1.Experience : Every situation is new when you are young therefore much more stressful/emotional. 2.Hormones : obvious but an 80yo is not getting the same surge of adrenaline for things as a 20yo. 3.Control : Old people general have money, options, connections, safety nets. Much easier to stay unemotional when something cant affect you. There didn't need a PHD for that....
