I 'd love to be able to travel freely thru time.
It 'd be fun to be able to adjust our outward appearances,
keeping our present knowledge.
I coud see going back to being a kid or young adult,
changing among ages. I 'd like to go back to the early 2Oth Century.
I had fun
in my childhood; abundant freedom, no problems.
It 'd be fun to do that again, with present knowledge,
especially with knowledge of the fact of the deaths of nazism & communism in the 1990s,
such that we were not
going to get over run by the nazis nor the communists.
