A man taking more than 50 tablets or capsules of many types of health supplements daily suffered from a mild stroke

P.C. Kingston is a good friend of my friend Lawrence H.Shaw.

Kingston is a 60- year-old man.

He is very knowledgeable in health matters and health supplements. He is considered a Health Supplements expert among his friends and relatives.

He looked fit (until last week) with well-gown hairs, not a strain of white hair.

For past several years, on daily basis, he has been taking more than 50 tablets or capsules of many types of health supplements he prescribes to himself.

But last week, he suddenly suffered from a mild stroke.

This shocked everybody around him. He is recovering well.

Can you tell me what happened?
