I'm 30 (soon turning 31). My parents/relatives didn't watch the show at the time, so I discovered it by myself many, maaaaaany years later.
It is truly one of the best TV shows ever
Higgins: Magnum, you are clad only in your undershorts. Magnum: Of course I am. Higgins: Even for you I find that just a trifle casual.

I'll be 24 at the end of this month, but I watch mostly older shows anyway.
To add to the European popularity, my brother's stay in Sweden in 2013 had him and my dad see Magnum with subtitles. (Not to mention in-store music over there plays rap music uncensored. )
38 until November. I came into Magnum during the 90s, and eventually returned to it with more appreciation back when Hulu had a good amount of free series.
I am 29. I grew up watching reruns on A&E network and have always loved the show. I joined the Army in 2008 and have just recently hit maniac levels of fandom by wearing a team ring and have several Aloha shirts and caps and such.
I have been an MPI fan since the original run of the series. Fortunately my wife and I got to visit Maui for 3 weeks for my 50th. It was then I fully understood why Hawaii is commonly referred to as Paradise. The beautiful scenery is just stunning. I am 60 now. In this pic I am with my best buddy Bosco (on left) for a few beers in the local and wearing the shirt he gave me as a 60th birthday gift. Our wives are present too but felt there was enough aloha attire going on !

I'm 37. I have memories of Magnum PI episodes playing on TV while my mom cooked dinner and we waited for my dad to get home from work. I've loved the show my whole life and only recently bought the entire series on DVD.
