Peter David, the current writer of X-Factor, posted on his blog yesterday that he had a stroke while on vacation in Florida.

We were on vacation in Florida when I lost control of the right side of my body. I cannot see properly and I cannot move my right arm or leg. We are currently getting the extent of the damage sorted out and will report as further details become clarified.

We wish Peter nothing but the best and hope for a speedy and full recovery. Our thoughts are with him and his family.
