Do you think your life would be different if you were immortal and could live forever?
I do, but I'm not sure if I would want an unending existence.
Why not? You would live without the fear of death and be able to do whatever you wanted to!
But, if you grow old at a normal rate...you'd be exempt from death, but you'd be old forever! lol 
But if you think about it even if you're old you're still living life. You still have the ability to breathe and engage in the normal things of life like walking the dog or having breakfast
Very true, with the immortality of the human body, maybe scientists would find a way to stop the aging process as well.
If science was advanced enough for immortality to be a thing it would be crazy awesome for them to be able to stop people from aging. That way living while being old wouldn't be as hard!
Yes, such as what life extension science is working on now. Of course, this hasn't happened yet, but you never know how close they are.
Hopefully someday immortality can be an option because even though it's scary to HAVE to live forever it is still such a gift to at least have that opportunity on the table
