with life comes illness, death and hardship. they come together like a package (since you got it for free anyway), and are inevitable. hence it only makes sense to anticipate and be ready for these events so that when they come, you wont be too lost or distraught.

one could even say that we spend our entire lives preparing for death, or rather for the moment before we die, where our lives (should) flash before our eyes. i would want to look back and say i had a life worth living. and since death could come knocking anytime, anywhere, it is better to live meaningfully everyday and without regrets.
