Die Leben des Lazarus Long. (Time Enough for Love)

The mix of space adventures and deep questions about human existence kept me hooked. I wonder if Heinlein planned this balance from the start or let it evolve.

His perspective on love contrasting with his desire for eternal life made me question what I value most. Am I the only one who found this tension unsettling?

The world-building felt so immersive and detailed—I'm curious whether Heinlein drew from existing theories or imagined it all from scratch.
