Pre-Test

A new procedure’s in the works
To test your blood for fats.
It’s 90% accurate,
According to the stats.

This test is being readied now
And based on the results,
The likelihood of Alzheimer’s
Will show up in adults.

So if the answer’s positive,
In two or three more years
It’s probable that you’ll encounter
One of your worst fears.

But when this is available
I know without a doubt
They’ll get no blood from me because
I’d rather not find out.
