Probably in days that's too overcast a good serving of fatty fish will help. Vitamin d3 is either synthesized from sun exposure or supplemented through diet, it is a good mood regulator.
The Executive can't pass laws, that's the job of Congress. Good luck with today's type of legislative bodies, too much political posturing and not enough common sense laws. Getting Congress to agree on anything is like herding cats. Actually herding cats is more doable with practice :/
