Paul Stamets, mycologist, talking about stuttering on the Joe Rogan podcast https://youtu.be/mPqWstVnRjQ?t=35m32s A clip of Paul Stamets and stuttering was posted a week ago on this sub, but he goes into further detail in this talk. Of note is that he recommends a mushroom (he takes in capsule form daily) called Lions Mane for its neuroregenerative properties. Lions mane is legal to buy and can be found at grocery stores (so he says). What do you think?
