I want to have a operation on my knee in this summer. Is it going to be OK? How is my year looks like? I born 10/18/42 .

Yes, it will be fine to have an operation. Don't worry! It will go smooth and then you will recover soon.

Your fortune will be of ups and downs this year. You should be very careful to handle all the matters in daily life. Be nice to people around you, one of whom may help you a lot in the future.
