So some someone asked the question what animal would you most like to be so I, of cause, over thought it to the point that it was not any fun any more. I am 58 years old. If I was a domestic cat I would have been dead for over forty years (plus I do not think I could eat a mouse). Garilers live up to 45, so I would still be dead for a while. A giant turtle lives over 100 years (in fact one is known to be 185) but I really wanted something a bit speedier. I also rejected Lizards, crocodiles and alligators. I want to be able to control my own body temperature and move around without my belly draging on the ground.
Elephants and birds would be amongst my choices, even if age was not an issue. African Elephants live to 70, that would leave me 13 years. The average life span of the Macaws parrot is 60 to 80 years and I expect they look good right up to the end, and of cause I would like to be able to fly.
The other alternatives I found were: Bowhead whales live up to 200 years, but are whales really happy? They might be ecstatic but how can you tell? Greenland shark also 200 years. Deep sea sponges live for up to 11, 000 years but my guess would be that they wish they didn't.
For me I think it would be between the elephant, the Macaw and the shark. I wonder if it is posable to create a cross species of all three. Then again that could go horribly wrong.
