Here's something rare about good people:

Did you know that there is a rare phenomenon called "Altruistic Kidney Donation" where a person donates a kidney to a stranger, without any personal gain or connection to the recipient?
Only about 1 in 100,000 people will donate a kidney in their lifetime, and of those, only a tiny fraction will donate to someone they don't know.
These selfless individuals are often referred to as "Angels of Mercy" and are considered true heroes in the medical community.
