Well, dunno if it counts, but I recently engaged in a data packet session, within a routing area containing low downlink latency in packet-based connections.

Which is just a geekier way of saying, I paged another cellphone user....

Actually, the whole issue of common and disposable "hi-tech" I think is an interesting one. For example, speaking of your "glasses", if they're anything like the typical pair these days, that's really an extraordinary amount of technology even right there. Being of the Geezer persuasion, I think my own are tri-focals ("progressives"/no line), w/anti-scratch and UV-coatings, plus they're also Photocromic (auto-darkening)!

And dunno why all that amazes me, but add in the cellphone & computer gear, the occasional prosthesis (dentures, etc.), hi-tech footwear & clothes, plus all the pharmaceuticals... and even the average person these days is just an amazing walking showcase of very advanced technology!
