I think that humor is important for people to relieve for a little while the stresses they are under, it is certainly a better state of mind than dwelling on things. Humor also can help you put things in perspective. What is deadly serious to you, or what you are worried about can be seen in a different light , that there is a humorous side to life and maybe problems arent as serious or deadly as we thought. Humor can also help to defuse tense situations. Satire, a form of humor, is a very powerful tool that people with little power can use against those who abuse their power. i dont think that you can train yourself to find certain things funny or not, its all an individual taste, as varied and complex as people themselves. What someone finds offensive many people do not . There is no formula on who is going to be offended by what. I like to joke around and sometimes i put my foot in my mouth but thats life.
