things i think i know, part 1

things i think i know about human bodies (and how those things relate to bicycles)

• humans are upright bipeds.  our spines point our skulls right up at the sky.  we are not stooped-over knuckle-walkers like other apes.  our bikes should allow our bodies to work the way they are built: upright with spines and skulls pointed to the sky.
• the delicate bones in the hands and wrists are designed to grasp and manipulate objects.  they are not designed to bear the weight of our torsos nor act as shock absorbers.  our bikes should not put our bodies in a position that places weight on the hands and wrists and forces the shock of every bump we encounter to be absorbed by our hands, wrists, arms and shoulders.
• there is a part of the human body that is designed to be sat on.  it is not the perineum.  our bikes should not pitch our bodies forward off our sitting bones.
• our heads weigh as much as a bowling ball.  our necks are desinged to balance that weight up on top of our spinal column.  our bikes should not pitch our bodies forward and force our necks into the position of hoisting upward that bowling ball.
