"I am married to an Indian lady (wife Shakira) and have learned about Indian culture. I looked into what they got and didn't get. And one of the things they don't get is Alzheimer's (disease). They eat a great deal of turmeric in their food. I have been taking turmeric tablets for 30 years and I have a memory like a computer. I remember everything." Sir Michael Caine, 80, on his trick to keeping a sharp mind.
