I know it has to do with the scale of the human body in relation to Planck's constant but can anyone explain it any further?

It's ok I worked it out.  

It's ok I worked it out.   It' because wavelength = Plank's constant/momentum of particle, and momentum=mass x velocity.   With a large mass (such a s person) the denominator becomes so large as to approximate the wavength to zero.

Yep.

 

In fact the only particles of matter that actually have noticeble wavelengths are electrons (and things with less mass).

Whew. That was suspenseful.
