There is lots of population research to support the fact that the elderly tend to be happier than younger folk.You make it sound wonderful!
Getting older doesn't feel like that for me. But it does for my parents. I'm hoping there's a turning point and it's not just due to personality.
I hope my ex-batts are happy, it's hard to tell ! They are a lot more easily afraid and I think they have grown more sensitive to the weather also.
We have less to prove, have less anxiety about what other people think of us, our expectations on life are lower so we are less often disappointed. Now of course health and poverty are big modifiers to all that, but generally we are a content bunch!
