I am sorry for your loss.
This reminds us all how short life indeed truly is. My father died in my arms when I was 19. He was 54. I walked away from that moment a broken young man but it taught me that life is too short to spend working 5=6 days a week.
I live a very stress free life now and have experienced more than my fare share of dreams. That only happened because I watched my father pass w/o having accomplished most of his. He was waiting for retirement.
Live for the now. You can't take it with you.
