you would have to keep moving because people would start to get suspishous when you are supposidly 70 and you have no grey hair
Ha ha, this. If I was to say "yes" to immortality, then I would need the addition of having the ability to move all over the place, AND change my appearance. Otherwise, it's going to get awkward really, really fast.
But honestly, I don't want to live forever, not in this life, anyway. The world is rather too risky to have an immortal body, in my honest opinion. There are many, many things out there that will be harmful, and unless our bodies can survive a hail of bullets without a scratch, meaning we won't bleed and be covered in holes, think of the media attention about this "indestructible person" if we are prone to accidents, and are able to survive massive damage. I wouldn't be able to shake the cameras off of me, and I wouldn't be able to live a peaceful, quiet life like I want.
In fact, actually, if our immortal bodies are prone to scarring, if we are involved in many horrific accidents, then it would be rather awful to go through. I don't care if I'm beautiful or not, if I look really disfigured, then chances are high that I will ask for death, because the pressure of not being able to interact properly with people who avoid me because I look ugly will get to me eventually.
But if we are able to escape being harmed and unhurt, then chances are people will get suspicious. Especially when it comes to aging, I'd have to move around. And chances are that if I were to be married, my husband will die old while I remain young, and if my body is unchanging, then there's a likely chance I can't have children.
I'm sure it would be interesting to move around the world, experiencing different cultures and learning new languages, but the world is changing for the better or for the worse every day. I will have to experience horrors beyond our imagination, and unless I can erase them from memory, I will remember them forever, and that's something I don't wish to have. I'm not a strong enough person to handle great destruction and evil than what is there before me today. My mind will break by the next century if I was to live forever.
And of course, there's the loss of my family and friends whom I've come to love. Sure, telling myself they're in a better place will help me move on, but I would get the feeling of being alone. There are billions of people on the earth, but I don't think I can cherish every single life.
So, I'd rather not live forever. I'm not that strong enough to handle it, even if I did undergo vast chances to have it so I can't get hurt or killed.
