does the angel stand on the side of the road to heaven and the devil on the side of the road to hell?

if we ask, "are you an angel?", both will answer "yes".

i wonder if i saw this on jpn wikipedia. is it the neatest logic puzzle ever? what's its history? any theories on solving it?

we'll go to this world when we die.
the protagonist wakes up and says, "oh, this one".

i don't know the answer either. you can even go without asking a question. some may suffer here forever.

>Best practice: choose meals based on salt content when eating out
this should've been salt content/amount. it was a mistake not to consider the mass.

one meal weighs 500g, or 5 rice balls. <1g salt/rice ball is recommended. (assuming one meal a day)
