Actor Ben Stiller believes it is important to laugh when things are not going good.
The 51-year-old actor says people should use their experiences to stay strong, according to Femalefirst.
"You laugh! When real life stuff happens to you, that's really not good, then it gives you some perspective. Real life stuff. That's when you go, 'Oh actually that's bad.'
"The movie not doing great, well, it's not great - but this person's gone or you have cancer or whatever. These are scary things that do give you perspective," says Stiller.
Stiller believes humour is necessary and everyone should use it to help them "navigate this crazy life".
"Humour is necessary in life for everybody to get through. I'm not talking about professional humour; just how we all as human beings figure out how to navigate this crazy life that we all are living that we don't understand really, ultimately. For me, that helps me get through it.
