You are right with the title of this piece, vanity upon vanity, that is life for us all, we have to see life as something ephemeral that would surely fade away one day. You are looking good now thanks goodness over some years of pain I'm happy to see you getting better. Soon enough you will be on your feet and practice a desirable exercise you want. Thanks for sharing your personal experience with us. Life is indeed vanity, getting more money doesn't make one happy.
