New research claims that drinking too much water killed Bruce Lee
The paper proposes that Lee's kidneys failed to excrete water quickly and efficiently enough

50 years after the death of Bruce Lee, a team of researchers is taking a second look at the cause. Though Lee’s official cause of death is the result of cerebral edema or brain swelling, what this new research supposes is maybe he didn’t. A research paper from the Clinical Kidney Journal proposes that “the kidney’s inability to excrete excess water killed Bruce Lee.”
Lee had multiple risk factors for hyponatraemia that may have included high chronic fluid intake, factors that acutely increase thirst (marijuana) and factors that decrease the ability of the kidneys to excrete water by either promoting secretion of antidiuretic hormone (ADH) or interfering with water excretion mechanisms in kidney tubules: prescription drugs (diuretics, non-steroidal anti-inflammatory drugs, opioids, antiepileptic drugs), alcohol, chronic low solute intake, a past history of acute kidney injury and exercise.
