If you could design your own body--give it any shape, size, color, contour, texture and elegant design--what would you choose?
What if your body could regenerate healthier, fresher skin and substitute worn out tendons, ligaments and joints with replaceable ones? What if your body was as sleek, as sexy, and felt as comfortable as your new automobile? These are just a few of the questions to consider in the decades ahead.

21st Century -- Body
Ageless
Replaceable genes
Upgrades
Error Correction device
Enlightened transhumanity
Intelligence Capacity 100 quadrillion synapses
Multiple viewpoints running in parallel
Gender changibility
Impervious to envirionment damage
Turbocharged optimism
recycles and purifies waste

Network sonar sensors map data
Infrared/ultraviolet-sensitive high-acuity single-photon-detecting, acceleration-resistant eyeballs.
Enhanced reality visual overlays through retinal implants allow you to view information on top of physical objects.
You can also edit your visual experience, removing unsightly objects and morphing scenes into images of your choice.
Sensory input can be patched in through global Net connection, allowing viewing of remote locations from Webcams, space telescopes, and flying micro-cameras.
External visual input gives you eyes in the back of your head.
Smart Skin

smart Skin of the future combines the historical evolutionary role of survival from the earliest of human ancestors, the Australopithecus, to our future Posthuman whose survival will be conditioned to a far different world than we realize today. The architecture of this transition is both biological, as our genes shape our lives, and technological, as we merge and mingle more and more with the technology around us.
The smart skin of the future will be a multi-functional design coalescing safety and survival, sensation and texture, beauty and elegance, fluidity and mobility, and terraced layers of what we know as the "self." It will function as an exterior protection and interior multi-function; it will combine artificial and natural design options; fuzzy membrane, both natural and synthetic; a sensorial surface; and ultimately square the curve of design.
Solar protected skin with tone and texture changeability.
Biosensors externally stimulate atmospheric tensions.
Active integument management system keeps all outer surfaces totally smooth and wrinkle free (unless you choose wrinkles for effect), and maintains maximal suppleness and instant response to sudden demands for stretch and twist.
Color control for instant blending in or standing out. Optional silicon carbide sheath enables you to become almost invisible.
ActiveSkin makes clothing unnecessary and allows you to display written or pictorial messages to convey mood.
Cardio

Flow and function monitoring.
Cardiac function augmented by high-powered turbine capable of pushing enriched blood through the body five times faster than a human heart.
The heart can be shut down and entirely replaced by the cardiac turbine, ending unfashionable pulses
Pressured nanobubbles contain extra oxygen supply to allow continued function for several hours in case of heart failure or drowning.
This is just an idea of the designs of future humans for sometime in the 21st century. You wont be forced to change so lets make that clear. Although the people who do change and upgrade themselves will be significantly more intelligent, powerful and beautiful than humans that choose not to use technology
