(Dan) True. If you see the sun on the horizon it is geometrically just below it. It adds a few minutes to daylight at each end. It's refraction (strictly, differential refraction) not gravity-bending which would need a mind-bogglingly dense earth. On Venus the refraction is so large the horizon is above horizontal and it looks as if you're living in a bowl. A hot one, 460°C. No oxygen. Occasional showers of sulphuric acid.

(Dan, Stevie) Nor the light in the boot of your car.

[rab] Isn't there a version of those ball-throwing arm extensions for dogs that you can get for kids? Alternatively, send him off to an aunt and uncle for the afternoon.
Merry Xmas, all.

Unfortunately the only aunt-uncle combo is based in NZ, so it'd be more than an afternoon...

AFAIR playgrounds are good. Choose one with a convenient bench from which to watch. Or join in if you're not self conscious. Something requiring concentration, like Lego can be surprisingly tiring. The best thing is to forget your boring adult lifestyle and simply play all day.
