Winter weather poses a different challenge for some health care professionals.
When winter weather blows through, there's a greater need for blood donations.
That's why WKYT is teaming up with the Kentucky Blood Center for the Call of Duty blood drive.
You can save lives by donating blood in this critical time.
You can donate Friday or Saturday at any Kentucky Blood Center location.
In addition to helping save lives, you get a long-sleeve t-shirt and get a chance to win a Wii, an X-Box or i-Touch.
