Well said, both of you. However, I would like to say that even those limitations that seem unchangeable truths of the human condition are NOT unchangeable! A thousand years ago it was a fundamental unchangeable truth that in order to send a message to someone a thousand miles away, it could take weeks to get there. Now, I can send that same message instantaneously; through the internet or by telephone. Even a traditional letter can be sent for next day arrival. Even better, if I have the funds, I can get down there and deliver my message in person!
That's one of the great things about being human. We see the rules inherent in our world and we seek out ways to bend those rules. We (well, some of us...

)are ingenious and innovative and we are not limited to lives contained within the abilities of our true physical selves.
