As a wise man once said..
"When the elders speak it is not because of the sweetness of words in our mouths; it is because we see something which you do not see. "
"You can live to be a hundred if you give up all the things that make you want to live to be a hundred."
"Nature gives you the face you have at twenty; it is up to you to merit the face you have at fifty."
"Do not try to live forever, you will not succeed." This is somewhat of a discouraging message but not if you accept the fact that there are limits on longevity, meaning that life has finite limits.
