Hi,
Sorry about your friend.
Age 50 is a killer!
The best tool and die guy I ever saw, a good friend, died one day shy of his 50th birthday. A month later I had a brain hemorrhage that should have killed me. I used to run distance road races. The docs said that is why I survived it. That squashed me. Really tough getting it back. I walk a mile or two everyday since.
I never meet you Internet guys, but it still hurts when you lose a buddy.
Daubie
