Pier Giorgio was very mindful of the uncertainty of life. Being a mountain climber and knowing how many lives the moutains claimed, he often took out life insurance before attempting a difficult peak. He wrote that one should "sort out one's conscience" before going into the moutains because "one never knows if one will return.""Since one does not know when Death will come to take him away, it is very prudent to prepare oneself every day as if one is going to die that same day." - Pier Giorgio Frassati
