As a general matter, anything that leads to longer life and/or better health is ethically good, but the steps that will lead to especially long lifespans may have some ethical problems for some people.

It has been suggested to me that the matter of transplants has ethical pitfalls, but transplants are a stopgap measure. The long-term solutions all involve using an individual’s own DNA and culturing new parts with the same DNA, but there are people for whom that is not an option, because ...

I don’t often think about it anymore, but lifespan is one of my many interests. A few months ago I wrote a blog about how people perceive time, and that is only one aspect of the matter. I have noticed that people seem to have a good idea of how long they will live. I have known some people who pretty much predicted their own deaths.

These are the Many Worlds referenced in the Many Worlds Interpretation of Quantum Theory (or THE THEORY OF THE UNIVERSAL WAVEFUNCTION, as Mr Hugh Everett, III titled his paper).

In the world that I came from beer was a fermented malt beverage that was flavored with hops and used a bottom ...

Possible impacts of physical proof that there are Many Worlds on the argument whether humans have free will and on time travel.

It has been known for a very long time that all events are governed by causality, the endless chain of cause and effect. This endless chain is widely regarded as determining everything, eliminating the possibility of free will in human activities. How can we truly have free will if everything is caused by causes that can’t even been seen because they occurred ...
