Jeez, no, not a cap on lifespan please haha. No one can still wrap in their heads what indefinite lifespans will mean, but I'm sure adding a cap on lifespan is not something we want to do.

Let's say we live in a world where human bodies don't age. How do you suggest enforcing that cap? Gas chambers?

Plain old accidents? No cap required.

I don't have an answer to your loaded question (https://en.wikipedia.org/wiki/Loaded_question).

Edit: link

The problem is that it's not really a loaded question, but a valid response to the idea of an age cap amidst indefinite life spans. How do you propose capping the life span of an adult without the use of a termination agent?

I am not proposing anything. I don't know how we can cap the lifespan of an adult. But I do know that if we have a cure for aging today, i.e. people stop dying from this day onwards, the population is only going to keep growing and that doesn't seem very sustainable. This is, of course, given that people continue to have children. Halting the production of new offspring could be interesting to witness from an evolutionary standpoint.

As far as the loaded question is concerned, I did sense an inflammatory tone in kobeya's response with the gas chambers question. Your response, on the other hand, is more discussion-oriented and open-minded.

Except it's not a loaded question at all -- administrative murder seems to be exactly what you are proposing.
