It is interesting and the company that makes it, Second Sight, was founded by Alfred Mann. He's the guy whose other company, Mannkind, just got its inhaled insulin Afrezza approved by the FDA. Mannkind has something called Technosphere for inhaled medications. I have always wondered if MANF would have any indications as an inhaled medication? Many love to talk about Elon Musk as some great inventor. Study up on Al Mann. He runs circles around Elon.
