48 ( popular age) and I watch every week because of TOS-R. I also watch the reruns on TV Land ( or where ever they show up) if I run across them while surfing. When the need arises I will break out the DVDs to double check my facts when discussing Star Trek on this BBS
And as other posters have indicated, I've noticed new things with this repeat viewing despite having seen each episode at least 10 times.
