The Catwalk - S2-E12
Other mistake: The Doctor states that sick bay is the most heavily shielded area of the ship but later in the episode he is trying to move all of his specimens to The Catwalk. If the sick bay is the most heavily shielded area then he would not need to move the specimens.
Answer: Acording to the Star Trek Encyclopedia Cochrane was born in 2030. His warp flight was in 2063, and he himself disappeared from Alpha Centauri in the year 2117 at 87. Kirk met him on a planetoid in the Gsmms Canaris region in the year 2267 making him 237. The first episode of Enterprise is in 2151, so Cochrane was missing for 34 years by that time and would have been 121 at that time.
