I can certainly empathise with your pain at 'losing something', as I can still remember what it was like to have above-average eyesight a decade ago, contrasted with my current 40% vision and no peripherals whatsoever. If it helps, when you see me at Aussiecon4, you can just label me as 'that dickhead' (and I'll be sure to come up and re-introduce myself as such. Pics at reasonable rates). That's what I look like, there, to the left. Dickhead. :)
