Miles Hilton Barber dreamed of being a pilot when he was a boy. But in his twenties he was hit by a genetic disease that destroyed his sight, leaving him totally blind.

His brother Geoffrey had the same condition. But the remarkable thing about these brothers is that they’ve both gone on to become record-breaking adventurers. The even more remarkable thing is that Miles (and Geoffrey) didn’t start adventuring until age 50! If you’ve ever felt held back by conditions beyond your control, or if you’ve ever worried that it’s too late to start, this story is for you.
