A reddit guy made this
The fandom make me feel like I'm the only one who doesn't need all those infographics. I mean, there is a wiki page.
So I did the math and kurapika lost 64 weeks of his life, also zushi had the potential that only 1/100,000 have compared to gon and killua having 1/10,000,000 where the hell is tseidnerrich because he learned all this stuff in half a day without being hit with nen afaik. Dude might be 1/100,000,000 or 1 billion even haha.
I have stopped doing maths a few years ago, but anyway it gave me a result of 1950days lost. Which would mean more than 5years.
Oito spent an hour on Marayam. If we take this as a standard, then she spent 10hours spying over the princes since the next prince was supposed to be Zhang Lei. It makes it 1500days, adding the three last hours it makes it 1950days lost.
There is 3600seconds in an hour. 3600x13(hours) = 46.800seconds (number of seconds Kurapika used his eyes). Now multiplying by hours because 1 second=1hour, then 46.800 x 3600(number of seconds in an hour)=168.480.000 (total amount of lifespan lost in seconds)
Now using google, it gives us 1950days.
This is how I have proceeded. Someone tell me if I made a mistake.

At this rate Kurapika's gonna have a heart-attack. Lamest death in shonen manga history.
