“General feelings of well-being and psychological satisfaction are linked to stronger resistance to common cold viruses, quicker recovery from illnesses (including cancer), and longer lives. When you feel better, your energy will increase; you will sleep better, eat better, and have more (and better) sex. People who have stronger feelings of well-being are perceived as more social, demonstrate more creativity, and tend to be well liked. Happy people more frequently donate their time to help those in need and are more likely to be optimistic about the future”
