Hi,

I want to tell you this:

Little is known about the perfect survivor, mentally and physically,

There is a small, very small page here debating/discussing the idea:

http://www.futurism.biz/wiki/Perfect_Survivor

Mentally here is an interesting point:

25) Freedom from instincts (a transhuman is not motivated by appetite
for food or sex)

But who knows what`s better..
