Thanks for posting that Peg. Very interesting.

Nice article. The experiments still being done that are pushing the limits of our gene research is money well spent, IMHO.

Nothing like peaceful use of identical twins in pursuit of science, especially since it was consensual.

I found this interesting...
Mark Kelly is six minutes older than his brother. But Scott Kelly says he’s actually a few milliseconds younger still, due to having spent 500 more days in space than his astronaut brother. Einstein’s special theory of relativity leads to a “twins paradox” in which someone moving at a high velocity, such as 17,500 mph in low Earth orbit, ages more slowly than a twin on Earth.
