Oh my gosh, I haven't thought about RD since Highschool when it was on public Television late night with Are You being Served and Waiting to Die or something like that ... "Waiting for God" was it actually. Those shows along with Benny Hill & Black Adder 1/2/3 etc. just cracked me up. I have a AYBS box set lol. I need more "Cunning Plans" in my life and need to get the Black Adder too
Anyways, in regards to technology, I would like to relive the experience of playing an NES for the first time at my cousins house and being perplexed by the Dpad & two buttons - what wizardry was this?!? (had only used a 2600 joystick up to that point) in the mid 80s and the first time I saw OSX on my friends new Titanium Laptop sitting in a coffee shop in like 1998 or 99 - the dock alone just blew my mind LOL. Those are great technology memories.
Non Technical memories would be the first time I heard my favorite band Mogwai. My buddy who I played music with handed me a burn of TenRapid around 1999 IIRC. I still have it - I'm sure, squirreled away somewhere in my stuff. I remember none of the music stores in my area at the time had Mogwai CDs so I cared for that thing like a diamond ring, making a paper CD sticker for it and repro case ... even bought some CD polish to keep it going until I was able to find a way to source Mogwai stuff (before the days of easy internet purchasing - I think my buddy Chris got that CD off something called eBay ... ). Anyways, Mogwai was formative in many ways for me musically. To relive the first time I heard New Paths to Helicon Pt1 off Ten Rapid would be so amazing.
On a personal note, I would love to relive the first time I kissed my wife and how that felt. I remember lightening shooting through my nerves starting with my lips. She made me dinner on that date which was green Chile chicken and cheese enchilada casserole with Pinto beans and Spanish rice. Mmmmmmm yum

and she had the greatest coffee too at the time which was a brand I was not familiar with called New Colony. reliving the emotion, the feelings & senses around that meal and the coffee too would be amazing. What a great date!
Anyways, I'd want to relive all those memories too.
