Can someone please explain wave particle duality for large bodies? Why don't large bodies exhibit wave like nature for example if I am walking with some momentum, the wavelength associated with me is $h/p$ what does this mean?

de Broglie wave length is defined as : $$\lambda _{B}={\frac {h}{p}}$$ So if for example your mass is 60 kg and you are moving with a sports car with a speed of 200 km/h, then your de Broglie wave-length would be on the order of $10^{-37}$m. No physical length can be smaller than Plank length which is $1.616\;229\times 10^{-35}\ \mathrm {m}$. Thus de Broglie wave lengths for macroscopic big objects means nothing.
