Knowledge is power.
We eat with a single hand and if we have four hands we may start eating with three hands. We may be able to do more work and turn out may increase.
To carry out a job, alone hands are not sufficient. We may require help from other parts of the body and we should have coordination with other parts. So to be more practical having more hands may not be of very much use to us. Our mindset only and our thinking capability will decide the work turn out more than hands.
The corruption will double. The corrupt will take bribe by four hands. Even with two hands we see corruption so huge. Imagine what will happen if the corrupts, bribe takers and usurpers have four hands?
Even with two hands the goondas and terrorists create havoc for innocent people. Can we even imagine without shivers those people getting four hands?
No baba, no, Let it be just two hands as is now.
I am also getting various funny imaginations about the fashion that would exist if we had four hands.
Our mind directs our limbs to work and our mind focuses on one work at a time. When two hands can't perform two different activities simultaneously, how four hands could perform four different works at a time.
