Better hearing

Low fat diet, NO ALCOHOL, no tobacco, wear hear protection when grass mowing and weed whacking, reasonable listening level, better speakers, etc.

BTW, in "unproved" a play on word or a fat finger for "improved"?

@dweller  what about hunting? I get extremely TIRED wearing ear-muffs and I like the sound of my side-by-side shotgun. Also FAT chicken or beef bone broth is good even if it's fat.

The bones broth of a cutted hunter with acute hearing is very good for improving our own hearing said my shaman adviser...😉

Yes, cannibals have excellent hearing (so I've been told).

Good deal, don’t make them have to tell you again.
