guys really... just use google and you get all your answers. but to help you even further:
"A follower's skills, health, and other stats are set when they are first created (which is typically when you enter their starting cell, become a Thane, and so on) and never improve from that point, outside of a handful of special cases. Each follower has a maximum level (which varies for each), and a specific set of primary skills, which are dictated by their class."
taken out of the page. so they do seem to lvl with you till a certain lvl, but their health, etc. does not improve much more. so nowadays counts still the same thing as months ago. the later you find a follower the better he is.
