If you have the means to stop aging in biology, you no longer need
biology. As such none of the limitations about what it means to be
human apply.

The only method you can profit from *right now* is human cryopreservation.
Most likely resuscitation mode from that arrested metabolism/biostasis
snapshot is by means of a destructive scan, and such abilities imply
existance of alternative substrates far surpassing biology. Due to 
cost and competivity reasons the bulk of posthuman habitation will be
off-planet, in a circumsolar cloud of solid-state nodes.
