Custom Bio-Tech Perks and Features

[Sindri]

To represent the effects of a society spending a long time tweaking and adjusting genetics to get rid of minor flaws and introduce minor advantages and because I think Vulcan Syndrome is a good source of flavour I'd like to compile a list of custom perks and features along the lines of No Degeneration in Zero-G, Taboo Traits, and No Appendix that can be achieved by gengineering.
