Cuz Hashirama isn't Asura. Plus, Orochimaru could. Danzou lost control when he was nearing his death. The fact that Orochimaru could means that its possible through certain modifications. Scientists spent years in studying this and they were experts. orochimaru managed to do it alone, so I'm sure if he could then the combined experience and efforts of these scientists could figre out how to modify the body in a way to avoid death.
