If I understand things right, Thailand celebrates the party that Dec 31 has become even though it has no cultural significance as a date to you. If so, I hope you had fun.
I went in for a hernia repair the morning of 12/31 (home by 2 pm) and have been taking it easy since. Everything seems to be fine except for the expected soreness. I will see the surgeon on Thurs and should hear his observations then. Back to work tomorrow. We will have to see if I do the entire day or not.
