I'm probably going to reveal myself as incredibly stupid and/or sheltered here, but... who is Gordon Lightfoot?
No, probably a different generation. He is a folk singer of fair prominence. He was better known to my parents' generation but I spent a fair amount of time delving into folk music. :)

Fossilising...but surely that's what all good archaeologists aspire to do
Actually, I aspire to being a freeze-dried Andean mummy. :) I want to leave maximum material to work with and I want a variety of translation dictionaries so I can be my own Rosetta Stone. :) And I want an Acheulean handaxe so that archaeologists can fight for YEARS over the significance and have feuding camps. And lots of people could get their PhDs off the controversy.

Not that you are old or anything.
Ah, I'm getting there. I don't creak yet and my joints all still work but I'm aware of time creep.
