4 seconds...
That time... Light can propagate 1.2 million kilometers.
That time... I tried to hold camera with its shutter open on something instead of tripod.
...
That time... Good car can reach the velocity of 100 kilometers per hour from 0.
That time... I can drink half litter of coke or pepsi in the bottle... But this is not good...
4 seconds....
That time... We can... We should have relax time, at least, for introspection.
