Lost

In summary, you are suggesting that we should not try to regrow human limbs because it is a difficult task that is not likely to be successful.

(there seems to be a problem as my last post seems to disappear unless I send another after it!)

I believe that it is possible and with time will be done as the progress that Mankind is making is exponential and the fact that it already happens in other animals even though they are quite different from us proves that amazing regeneration is possible.

<h2>1. Why can't humans regrow lost limbs?</h2><p>Humans are not able to regrow lost limbs due to the way our bodies are designed and the limitations of our cells.
