Glad he is doing better. DH had a stroke 5 years ago, he is mostly better now.
PLEASE learn the signs of a stroke. If you think someone may be having one, do this simple test.
1- Ask them to raise both arms equally
2. Ask them to smile
3. Ask them to say a simple sentence.
If you see they have difficulty doing any of these tasks, get them to the ER right away!!
PS - strokes are not just for old folks, people of any age can have strokes, even children and babies.
