He called him when he was working in Manila and told him about the headaches he'd been having. They continued through the 20th until he collapsed at Betty's place. Alkaloid chemicals in the cannabis were causing it. Dr. Wu told him the next time it would worsen because he was under a lot of pressure. The last time Bruce saw him was in June and had no complaints. Bruce should have went to Dr. Langford. He had his business card with him the 20th when they went through his clothes. Unfortunately...It is terribly unfortunate the circumstances surrounding that fateful day/night for Lee. Even immediately after death, he was just left... alone.
