      We can’t regrow limbs because the cells in our body are too mature (i.e. too old) to regrow. So although we have cells with this sort of ability when we are developing in the womb, we do not have this ability as adults.

      Our bodies are not built for it. The Axolotl is famous for this ability. Have you seen what some scientists are achieving artificially? So not such a dream after all, just hard work
