That (Fantastic Fungi) was perhaps the best documentary that I’ve watched in years.. Amongst other things I took the following from it..

1. Lion’s mane mushrooms have potential qualities which MAY be able to assist in combatting conditions such as Alzheimer’s disease.. but they are rare and at least here, picking them is apparently illegal.. they can be grown though.
2. I really need to experience psilocybin (magic mushrooms), as soon as possible, please.
3. I need to read, Mycelium Running - and will purchase before I go to bed..

.. I also then answered my own question of what to do with spent grain when I become a brewer (not going to give it to cattle farmers.. as most people suggest..).. I’m going to grow a fuck tonne of mushrooms!
