for important medicine, I believe

for

should change their system, and be punished if not.

I believe

procedure should be avoided since there is a lot of suffering from the

, while the tests are performed, as shown by some studies. With the new advances in technology, maybe it is possible that one day we do not need the

for producing any product or studies, as well as for our own consumption.

For instance
