gemini man starring ben murphy and alias smith and jones

I think there is something missing from my brain (some would say a lot).
I used to love 'Alias Smith and Jones' when l was younger ("Starring Pete Duel and Ben Murphy"), but didn't realise that Ben was also 'Gemini Man', a character who could make himself invisible using his watch. That series has either just passed me by (unlikely), or l have just forgotten about it completely (which seems to be the case). How could my tiny little brain do this to me? What else have l forgotten? What if it has wiped out something l need to remember? What else is it doing to me?
I need a lie down (or is my brain just telling me that to take my mind off this subject?)
I'm confused.
