Get your cow, cowboys and cowgirls...

...and let it lead you to Santa with your wishlist:

But seriously, the reason why cows point their head north might be that wind from north is cooler than wind from south, and then they avoid in larger degree udder (and bladder or uterus) infection if their udder and other vulnerable parts nearby is protected from cold wind. Combining that with daylight and the tendency of facing north is preferred through evolution.

Mystery solved?

Higgs Boson

If it's there, then perhaps another particle that it interacts with? I can't imagine just one single type of particle (and perhaps only Higgs field?) that just stays there... everything is in motion and interact with (opposite) particles with near same physical qualities.

My guess would be two particles that change phase so swift that they don't annihilate each other, and that the interaction/vibration between the particles curves space so that the motion inward is slightly faster than outward - explaining both mass and gravity.
