The baby's soft body just got squeezed through a tight passage from their head downwards, which means they already lost blood back into their mother. So who are we to discuss what WE will do with the blood that would still flow back into the baby immediately after birth ??? A recent study (which I won't bother to dig up) showed that leaving the baby attached to the mother for a few minutes greatly increased their blood volume, even months later, which would seem significantly improve their health. This whole consideration is another disgraceful example of heartless science treating voiceless people as material "resources".

Biggest problem with a mouse is having to move the right hand back to the kbd to press Enter. However, by positioning the trackball just to the right of the kbd, you can use the right thumb on the second Enter key, making many operations much faster.
