You have to balk when anyone says that anybody is the same person they were 24 years ago.

You have to disbelieve anyone who says they aren't a derivation of their previous person states. That's just physics.

Oh you have a comprehensive physical model of individual human behavior do you, in particular the decision making process of life-changing choices? I'd love to see the publication.

This is too simplified. What is the state of a person? It's an object of infinite information, the question what aspect you focus on is very non-trivial.

You don't have to disbelieve anyone who says a certain aspect of a persons life typically has little influence on their later life. Another issue is that for some a particular event might be life changing and for some the same event might be a nothing burger, for no obvious reason.

Sounds like homeopathy more than physics.

You have like zero molecules left in your body from 10 years ago. If you are worried about physics, the most important consideration is your diet.

And are you really a derivation of your state, or of the things that happen to you? The guys who were drafted into war in Vietnam and then got killed there, was there anything about them that would have made a difference to their cruel fate? If we go by this philosophy, the most import decisions are when you were born, where, and into what environment.

For example if you want a house, you should have timed your birth to 30 years ago.

A big part of what makes a person is their unique collection of experiences.

You can be the same person but different because of those experiences.
