My good friend died unexpectedly at the age of 40 from liver failure. Turns out, his liver was compromised from 25 years of exposure to paint chemicals being in the auto body/restoration business. He admittedly didn't take proper measures to protect himself during those years. Having said that, he was an alcoholic who drank excessively, daily. The last year of his life his drinking elevated from beer to vodka. Although it is true I will always say he died at 40 because of both factors, ultimately I feel it was the booze that took his life.
I don't know the circumstances in Jeff's case but when I hear "spider bite" and yet see photo after photo of him with beer in hand (let alone the lifestyle)...It's hard not to think of my dear friend who I truly believe would still be here if he had a better handle on the booze.
Something tells me Jeff's case is similar.
IGNORE THE NOISE!
