I am 100% happy with the way our bodies are designed

Particularly the Woman's bodies.

Particularly Jessica Beale's body.

Thank you evolution!

Mate, I have shagged a few birds with a chest on the back and front. Funnily enough no nipples on the back..

As for the stunning Jessica

she should be cloned, so we can all have one (or 3) for our own..

Hey Winston,

For me the most amazing pasrt of the human body is its ability to recover from serious trauma.

I would also suggest that the brian being placed at the top of the body in the thick skull to protect it; must have seemed like a pretty damn good idea at the time. I'm not sure the 'Big G' had anticipated the motorcycle as a reason to modify the design.

Snakes seem to do a pretty good job of defending their brains and I have heard it stated many times that the Shark is as close to evolutionary perfection as you can get.

Neither snakes or Sharks ride motorcycles
(or at least I haven't seen one)

Good luck with the healing.

the chest cavity has one or three other rather important organs taking up space.Highr in the hierachy than even the brain...ie heart and llungs

Wouldn't it make sense that the brain is as close as possible to the sense organs?

Thanks, I'll bear that in mind...

Is that where the expression,"He thinks with his dick!" comes from...?

My brain travels in an orbit of about 3 feet

Neural signals from your senses travel at a limited speed. All the important sensory organs have to be at the front/top/ of the body. The brain has to be as close to your eyes, ears and nose as possible. If it wasn't, the resulting delays in the transmission of signals to your brain would naturally de-select you pretty quickly.

I've wondered for some time about the efficiency of creature's bodies - including homo sapiens. Almost every animal has a head situated upon a neck. Within that head resides the brain which is the critical organ for survival. Mammals, insects, reptiles, birds. Fish are the exception, and even then the brain is at one end. Not sure about amoeba and bacteria.

Now, the brain is so important that I can't see why evolution would allow it to sit in such an exposed position. Why not position the brain in, say, the chest? By all means have a head with eyes and ears, but for goodness sake protect the machine which is critical to survival. And the brain would then be closer to the spine for running the central nervous system.

There's another thing - why expose the spine on one side of the body? Yes its needed for skeletal purposes but why not a central spine with two rib cages?

After all, our bodies are complex constructions anyway and these variations wouldn't be any more strange than what we already have.

So I'm interested in your ideas.

I heard you had taken a knock to the noggin as well Winston.
How is that coming on today?

Interesting queston.

Eyes at the front..........spine to the rear..........where it can be best protected.

The rib cage is the first line of defence for the spine from a frontal attack, that's excluding the arms which can be used to defend the rib cage.

The brain is pretty well protected within the skull and neck mobility lesson the shock from any sudden blows and I stress lessons the shock.

Interstingly the sex organs are placed in the best protected part of the anatomy that is until we started walking on two legs. They became exposed as a result of bipedial movement.

You can get arrested for that...

Well knock me down and call me a primate - I'm impressed as all get up at the intelligent replies here. Very good thoughts.

As I understand it, the basic animal layout of bilateral symmetry plus head, gut, anus with backbone comes from our fondly remembered ancestor, the flatworm. http://www.sciencedaily.com/releases...0322062150.htm

So we've been stuck with this body type for 500 million years. You'd think evolution would have continued on a bit further....

Also evolution is progress by chance, not design. If it works then that becomes the forward plan even if it isn't ideal.

Can anyone think of a creature design (above the level of microbes) which doesn't conform?

There is a school of thought that motorcyclist spinal injuries are related to the extra load of the helmet.

The arrival of the heavy crash helmet in the 60s and 70s co-incided with a large number of extra spinal injuries.

By the late 70s, NZ had two specialist spinal units, which remain to this day well stocked with bikers.

Last week on the television the head doctor from Burwood spinal unit was quoted as supporting the ACC rises due to the large number of bikers in his care.

Many studies have been done, which clear the helmet of blame.

I for one, am not sure. The physics of a helmet add extra weight, extra torsion and an earlier contact time to the dynamics of a crash.

I for one choose the lightest helmet I can get.

If common sense counts for anything these days, than it would seem reasonable to me that attaching 1300grams plus to your head would only increase the stress felt on your neck in a crash, ie same velocity + more weight = more neck ouchies..

That is logical. However.....the protective shell of the helmet absorbs a huge amount of blunt force which would otherwise be transmitted directly to the skull. That in turn would be transmitted to the brain and trust me, you don't want that to happen......

The problem with the mass of a helmet is that it adds torsion and compression to the neck, none of which is acceptable to a healthy spine. Therein lies a problem.

The only answer I can think of is a neck collar to stop the helmet compressing and twisting - but that would make a helmet unwearable on a sportsbike. Or there may be airbags for this purpose.
