Oh boy.. Tim. I'll certainly be offering prayers for your speedy and complete recovery. You are like an oasis in the bleak barren desert that this group has become. We do need your positive contributions.
A couple of months ago I brought this subject to my doctor. I complained that we didn't have an easily accessible diagnostic program to check us for potential problems like clogged arteries. His response was to change my lifestyle now to head off problems.
Best of luck to you over the next few months.
