The night before 12 midnight onwards, Keith had to start fasting. The appointment was on 830am. But the actual operation start at 11am. It only took about 30mins and he was out of the operating theatre.
After that, he was kept at the day care unit till he is ready to go home... thus by the time he regain his energy, it was almost 430pm.
The picture is the screw and washer that was in his arm for more than a year.
