Evolution revelation
Next question - what makes an assymetric brain a better evolutionary result than a symmetric one? i.e. why do we have a right half and a left half instead of two of every segment and lobe? Is it because the benefits of a compact brain outweigh the benefits of a brain with contingency redundancies? In other words we could not have managed with a brain twice its current size (even at its current size it makes childbirth the most dangerous amongst all living creatures, especially because we also wish to walk erect). In fact why have some organs evolved with redundancies (kidneys, lungs) while others have not (heart, liver)?

Is this only true of humans or do any other creatures indeed possess redundand brains?

Weigh to go
Seems my previous question was not clear enough. Let me be explicit. My question is more in terms of biology, ignore minor physical effects like change in center of gravity :) and you are not in a closed system!

I extend the scope of the question - how would your weight vary during the day if you were to take a measurement at various points.
Specifically, consider the following:
1. Just before you sleep - say you weigh W1
2. Immediately after you wake up W2
3. Brush your teeth and take a dump
4. Eat Breakfast5. Coffee Break at Office
6. Working Lunch at office
7. Post lunch coffee break
8. Evening pack of chips
9. Go drinking with friends
10. Dinner back home

Place readings W1-W10 in ascending order (i.e. lowest to highest). And of course, provide reason :) Please think about this hard because I suspect the actual answer is not as straightforward as it may seem - I have tried this experiment to an extent but the results haven't exactly been what I expected.

Munch and Crunch
You have a highly sensitive weighing machine. You weigh yourself and an apple independently. Then you weigh yourself and the apple - and then start eating it. What will be the effect on the reading as you continue eating (if any)? Will the reading after you've finished by the sum total of the individual readings?
