I was wondering, if there was a music band consisting of five members, and every two years one band member left the band and was replaced by a new musician until ten years had passed and all five original band members had left. If those first five band members formed a new band then which band is the original band?
The new band has the five original band members but it is a new band and the band they left never stopped existing throughout the ten years but they don't have the five original musicians.
Why do I hurt my brain :-| ?
