When my brother was working on the new pool on our land in Bay City (SLurl; his land, really) he added some fences because we all know that if an avatar falls off a 10m tall prim they are seriously hurt. I thought the barriers were attractive despite being a bit LI-intensive (5 LI for one section and linked post) for mesh. The next day I saw he had lowered the fences and I asked why. He told me "Try looking around at eye level."
This camera position-created distortion probably explains why doors and windows in Our World are so out of proportion to what we might find under similar circumstances in the Real World. And I would not be surprised if both the distortion and the outsisizing of avatars are related, one affecting the other in a cycle.
