What are some of the benefits of being happy?

Happy people experience more tangible benefits.  They are likely to have better work outcomes, be more productive, produce higher quality work, have a higher income, and are more rapidly promoted.  Happy people also have more friends, more satisfying romantic relationships, and stronger social support networks. In addition, happy people also have better health, fewer physical symptoms and are able to deal more effectively with pain and illness.  There is also a lower incidence of depression, quicker recovery from surgery, and they actually live longer than people who have lower levels of happiness.

Thanks for taking the time to find the right answer. This is going to help with my final exam review.
