Not the length of your life that matters yet the quality/depth/soulfulness of your life( to live life to the fullest no matter what + to live every day as if it could be your last) + making kindness/love a priority-that makes life meaningful + when you die you will live a great legacy for others. Yet, would be fantastic if everyone had the same life expectancy all over the world for sure, yet, even in the West there are no guarantees of living to a ripe old age due to various illnesses/diseases or accidents/tragedies. To me, there appears to be a real generosity of spirits/kindness/stronger communities + smiles that could melt the hardest of hearts especially amongst the very poor particularly in developing or third world countries. Standard of living is higher as are our life expectancies in the West yet that deep Happiness somehow appears to be far less common amongst the Western World as a whole probably as there is too much emphasis on the shallow matters + a murky cloud of cynicism embraces far too many individuals. All that is precious in this life are free for us all ( family, friends, love, kindness) so agree with Slooow_Jo :-)
