I'm still only 22 but I feel like I've existed for far too long at this point, the thought of even reaching 27 is such a dreadful thought to me but it does make so much sense to me why people choose to voluntarily exit this world before they reach their 30's.
I see no benefit to ageing and inevitably deteriorating just to die anyway and I believe that the problems and suffering that humans go through just increase as time goes on and this fact makes the thought of non existence sound so incredibly appealing. In my case, it would had been for the best for me to have left this world as soon as possible.
