that's ez. The real challenge is doing it in one day without speeding it up.
there are 61 avatar episodes.
Each episode is an average of 20 minutes
1220 minutes
an hour is 60 minutes
1220 divided by 60= 20.333333
That means that you would have to spend 20 hours, 33 minutes, 33 seconds and 33 milliseconds of your day to watch avatar.
Now I don't know about you but I have shit to do.
I also get sleep
These two setbacks make this challenge extremely difficult.
The way to beat this challenge is drinking energy drinks to not fall asleep and to get all your shit done beforehand or just run away from your problems (your choice)
Although it is possible it is very challenging and will take a toll on you mentally.
