They go to work in the morning ?
Diff hair and facial hair sometimes esp with men and middle+ aged ladies. Tend to be louder. What they're wearing and how they're wearing can also be diff. They look at people and things for a longer time like it takes them longer to process something or wasn't taught to not stare (this last bit is true with another demographic too).
Generally, what they observe and what piques their interest or catches their attn can be diff too. And other little things like what they drive, what they order, how they speak, etc. But generally you can tell right away from first glance at their face.
