Just tagging this for the future.
Considering an older member of society

EDIT:
I feel like I should ask.
What is the technology for synthetic bodies looking like?
Are memetic viruses (for instance, a sequence of flashing lights which infects an optical modification) a thing?
Can one hack an implant to produce more mental strain/capacity than it would normally require (For instance, forcing it to run one billion instances of BonziBuddy)?
Aside from vehicles, what else is Geonet required for?

To answer the last question:

[quote]Despite the poor conditions of the cities, there is one luxury that makes life there tolerable: Geonet. An upgraded internet with lightning fast connection speeds and overseen by a powerful AI; all citizens are connected to Geonet and their GEO-IDs serve as a means of identification as well as keeping track of their personal information. Using their GEO-ID, citizens can readily keep track of their money, health records, and even access public transit. A GEO-ID is typically a small green disk that’s linked to a specialized armband, but it can be attached to different articles of clothing (i.e. glasses, earrings, rings, etc.) or it can be directly installed into a citizen’s cybernetics. Due to being DNA locked to an individual, stealing or masquerading another person’s GEO-ID is NEARLY impossible. Despite GEONET being one of - if not the only - useful thing in the Megacities, there are some who elect not to use it, preferring a life of freedom without the watchful eye of City-Security on your back.[/quote]
