It’s impossible, unless you’re a star. Helium is non-reactive, so it would never be part of digestion or respiration except in the normal trace amounts that already exist in the air. Stars, OTOH, “consume” hydrogen and “excrete” helium, so Rygel must be fusion-powered. 
Yeah. I want to be fusion-powered also. Where is that frakkin new body anyway?
