In Thor: The Dark World, Jane Foster stumbles upon the Aether. It attaches itself to her. She then carries it around for much of the film, which seems to cover at least one full Asgard day in universe. The medical people on Asgard state that the Aether's energy will eventually kill Jane, but she is able to carry it for quite some time.
Contrast this with the Tesseract and the Purple Power Stone. When Red Skull held the former, he was beamed somewhere. Admittedly, Nick Fury was able to hold it briefly with no ill effects. The Power Stone is quite lethal to most anyone who tries to wield it briefly. Only by fusing it with his hammer was Ronan able to wield it, and Star-Lord needed the assistance of most of the Guardians to wield it manually.
Which brings me back to Jane. She had minimal issues carrying around the Aether for hours upon hours. There were some side-effects, but that's nothing compared to the other Infinity Stones. Is Jane superhuman, or is the Aether oddly easy to wield?
