This is People Fixing the World from the BBC World Service,
a show that reminds us that we can change our world.
I'm Myra Anoubi and today I'm going to be taking you on a journey inside the human body to find out how each one of us can be a lifesaver.
Let me take you back to December 1954 to meet the Herrick brothers,
twins who would go down in history for being part of a groundbreaking surgical procedure,
an organ transplant.
Ronald Herrick became the world's first organ donor,
offering one of his own kidneys to save his identical twin, Richard.
The surgery was successful and it opened up a whole world of possibilities to help people whose organs were failing.
Now, more than 100,000 transplants take place every year.
It's completely life-changing.
I mean, my life has been saved twice now.
That's Lisa Pengali.
She's one of the lucky ones.
