Do you have an Air Miles Card?

Speaking of barriers to interstellar travel, are there any plausible solutions to the issue of radiation?

edit: Regarding the issue of "changing the human body," I personally consider stuff like "the elimination of aging" more plausible than stuff like "being able to 'upload' the brain" (or otherwise allow the mind to be divorced from the human body). The latter I think can basically be filed in the "similar to FTL travel, basically magic" territory.

It's not entirely outside the realm of possibility that in the distant future our civilization is replaced entirely or mostly with machines, which may be less susceptible to radiation.

There are also extremeophiles that can survive intense radiation. I don't know of any reason that genetic engineering couldn't achieve the same given enough time. This doesn't seem like a "laws of physics" issue to me.
