1 and 6 are my favorite on the list. I try by all means to exercise it everyday, being kind and loving people goes a very long way and doing it for no reason goes an even longer way, there has been times where i have been depressed and a stranger just smiles and you could see the love within they smile and they don't even know what your'e going through but that smile just heals you completely... i also believe that you live longer if youre naturally a happy loving person
