A warning

An iron hand, a vicous bite,
Pulling, tearing, with all it's might.
You clutch, you gasp, you try to breathe,
Praying that the pain will leave.

The warning symptoms all appear,
Warning of the end so near.
You close your eyes and pray for life,
As the gripping pain tears like a knife.

Your heart is thumping, its on a run,
But this one time, it's not for fun.
The pain is warning of your health,
That it can take you with its stealth.

Learn young, live long-- to survive,
That's the way your heart will thrive.
