Who'd want to live to 150?
That's about 60 years in an old folks home, having somebody else wipe your arse. And you'd have to work until 90 to pay for it.

That will mean the abolition of retirement. It will impossible to save for a long retirement with a limited career of working. Though you could probably work till 120 and then have 30 years retirement.

..... At some point in your 150 life span, you'll probably wish you were just dead because it's all just too much.

TBH, I don't think anyone knows just how long the human body can be kept going for. We also have to ask if the planet can support a population which just will not die.

Star Trek covered it in the The Mark of Gideon episode.

It is a cure or a vaccine? From the article it seems to be used to prevent degeneration of the brain and not rebuilt the brain (which makes sense).

My grandmother is currently in the violent phase of Alzheimer and I really would much rather not become like that.

It prevents prions and bad proteins from causing brain cells to die, so it doesn't cure the problem but prevents symptoms from developing. It's like the drugs that help prevent HIV from becoming AIDS.

However, it is unknown how hereditary Alzheimer is caused so it may not work in this case.

If it can reduce the numbers of Alzheimer's by say 80% then it could mean that we as a society should have less problem providing financial support for those that have family members who still get impacted by the disease.
