to use non stop walking speed as a measure

but again....would love some data

they probably meant walking half day

a walking day. dawn to dusk.

but cut in half

still a big number

how far can a persons eyesight reach

is it infinite?

like some globers say

mine? only about 10 feet now 🙂

mines getting worse

im at around 4ft

lol

without spectacles

I'm now at the reading glasses stage

really bites

but you can correct it

via vision exercises

eagles have 3x our eyesight apparently

a peer in grad school corrected her vision from -4.5 in one year

I was envious but lacked the motivation at the time to try

c&p: The farthest point you can see is about 3 miles out. 6 miles: The average 747 passenger plane flies at about 6.6 miles up in the air

can I just add something interesting

sure

this is not in the quran

its in some books

its in the hadith

it says that after judgment day

the good people will be given their first meal

and this first meal will be the liver of a fish

and they are told that it is this fish that the earth was inside off

or something like that

what a first meal , , hopefully the 2nd is more appetizing

lol. though I've never had fish liver.

don't knock it until you've tried it

yeah, maybe we've just been missing out all our lives

its probably just a myth

though the Bible also describes a feast

hhm, inside a fish okay

though no mention of the food items

the substance that rocket hit did sound pretty fishy come to think of it
