While still of course afraid of actually dying, instead of being perennial fearful of death I am instead now grateful for being alive this day. Try that change in perspective.

Background anxiety about our "eventual demise" is the consequence of false entitlement to life and health. Young and healthy people imagine good life without end, the dying and people who've lost health and ability often know better.

This change in perspective also helps you make the most out of each day, because those who make a point to remember that their good days are finite will not want to have spent them in waste.
