A certain amount of stress keeps you excited and revs you up to go places and tackle challenges.
Most people can take a lot of stress.
Of course, some can take more than others. No matter who you are, however, there is a point at which too much stress can begin to get you down. Some people close others out and prefer being alone. Some people feel tired and blue and want to talk to someone else, like a best friend. Lots of people, young and old, get headaches or stomach aches.
