You probably already guessed it. You knew the food that tastes good is bad for you. Now you know that happiness, or the pursuit of it, is not a happy thing. According to an article in Science Daily:
Trying to make yourself happy may fail, causing unhappiness.
Extremely cheerful people die younger than those who are not.
There. Are you happy now? I hope you’re happy now, damn it. (Yes, it’s one of those articles with little practical and meaningful information, but I couldn’t resist.)
