how do you spend you 40th birthday and do you feel old?

I did not feel old on my 40th Birthday and I don't think you should. I had the most wonderful 40th Birthday ever. I had a surprise party on a river with everything catered, all my best friends attended. Then to top it off there was a midnight cruise on the river. It was so romatic and beautiful! Enjoy your next 10 years because by the time you reach 50 you will begin to feel old.
