The problem is if ya test positive, it will cost you a fortune for treatment, unless ya got gold plated insurance, or ya happen to be a government employee.
It’s not a matter of positive, it’s a higher from year to year that counts.
They not only keep track of you from year to year but forward the test results to your doctor as well as you.
Someone told me that they wern’t going to test anyone over 74 this year.
I’ll find out since i’ll be 75 when I go to the show this year.
