Ancient Greek athletes allegedly had their spleens removed to improve running speed.

Infact verdict: Mixed (53/100).

The claim that ancient Greek athletes had their spleens removed to run faster is based on historical beliefs rather than verified medical practices. The evidence from Britannica suggests that some ancient Greeks believed the spleen hindered running speed, and some runners may have had it removed. However, this practice is not widely documented or corroborated by multiple sources. The claim is more of a historical anecdote rather than a verified fact, and the evidence is limited to a single high-quality source.
