It’s not always the most optimistic outlook that helps you into LONGEVITY. What IS necessary is a sheer determined view that you will do what it takes to get there. That view is not always having a happy go lucky optimistic view, but one of ‘damn the torpedoes’ mentality 

It is better to be happy, and cheery, AND taking the daily necessary steps to make sure you can stay that way. Sometimes it is absolutely adamant to make the hard choices, do the hard things, and even give up some daily habits to get you to be not only alive, but LIVING well into your 80s, 90s, and even 100s. 

It is what people who live the longest do.
