Though Trillans are almost entirely non-manual workers they do spend significant amounts of time outside and travel to different parts of the world on a fairly regular basis, as such Trillans tend towards a universally slightly tanned complexion.  Trilla has slightly higher gravity than Terra but this is not sufficient to produce high-gravity characteristics in the population.  The Trillan population is generally very healthy as a result of a combination of the good healthcare provision and substantial amount of time spent outdoors.  While allergic reactions to the pollen of the crop plants grown on the planet is very uncommon amongst native Trillans it is important to note that visitors from off-world regularly report problems during the main flowering seasons.
