Being a climber does sound more adventurous and tempting, and there are a few situations I can think of where higher ground = safety.
Still I picked the floater--seems like it has more lifesaving potential than the climber, and I'm more wimp than adventurer.
==========================
Would you rather live in a world where computer and console and mobile games (including Lemmings) never existed but the Internet does, vs a world where the Internet never existed but computer/console games does?
[I originally just say "Lemmings", but think it will be more balanced to include all computer games rather than just our beloved one.]
[edit: included console games as well to further up the stake]
[edit2: added mobile games (cellphones, tablets, etc) as well. Goddammit, too many kinds of computing devices nowadays!
