There are tons of companies researching methods to increase life expectancy and rejuvenation. There is not much controversial about it yet.
It is not that it is hard because it is a controversial subject. It is hard because it is not one problem. To develop rejuvenation you would need to tackle hundreds of very difficult problems, both physiological and neurological, which individually, would represent solutions to critical conditions today (diabetes, dementia, ataxia, arthritis, many types of cancers etc etc).
