Thanks for commenting. Although I have heard about “gene therapy” (and a little about transhumanism) I doubt that either of these will be available in the next century (if not greater).

Drugs often have side affects, and if a “miracle drug” comes out, it will have to be thoroughly tested in order to insure safety.

The closest “helpful drug” that I can find is the anti-radiation drug although to my knowledge no drug exists that could effectively counteract our bones and muscles from atrophy.

If something comes up, let me know, but until then I’ll remain the “hopeful skeptic” in the medial arena.

But is it really that hard to imagine reengineering our bodies to make them stronger? The way you write makes it sound like you’ve never heard of gene therapy or transhumanism. If we have the technology to move millions to other planets, then we will also have the technology to artificially induce bone and muscle growth, and protect ourselves effectively from solar radiation.
