Keep your grounds as short as possible and as many as possible

I don't work on PCB layout design (much) myself, but have many friends and coworkers who do, and actually your advice is very applicable just as a general design rule, any nuclear threat aside.

Especially as frequencies increase for our circuits proper grounding is very important.

I should have also said to keep the grounds as short and equidisant as possible. Unequal grounds have a cummulative effect.
