So what 80 years of life, for your grand daddy, this is an amazing life, you and me, i am not sure if we could get this numbers of year old in our life.
But well we need to make a better decition with our time, and try to eat more healty and get out of the city and go to the forest or mountaing more fast, and spend a little more time in this kind of place.
do not worry the time pass but we here with life, maybe not in the best situation but we should try to live very well.
Best regard.
I think he had a pretty good life all up - seemed to enjoy his aging too.
Hopefully things are going well enough for you at the moment and in a year or two, things will be better again :)
