Since we started talking about bruce lee, my curiosity was peaked. Here's what I found about how he died.
http://en.wikipedia.org/wiki/Bruce_Lee
"A short time later, Lee complained of a headache, and Ting Pei gave him an analgesic. At around 7:30 P.M., he laid down for a nap. After Lee did not turn up for the dinner, Chow came to the apartment but could not wake Lee up. A doctor was summoned, who spent ten minutes attempting to revive him before sending him by ambulance to Queen Elizabeth Hospital. However, Lee was dead by the time he reached the hospital. There was no visible external injury; however, his brain had swollen considerably, from 1,400 to 1,575 grams (13%). Lee was thirty-two years old. On October 15, 2005, Chow stated in an interview that Lee was allergic to Equagesic. When the doctors announced Bruce Lee's death officially, it was coined as "Death by Misadventure."
I wonder if anna suffered the same fate.
