it's not a desireless person. it's an addicted person. you are trying to pretend addiction doesn't exist. i've met so many meth heads that wish that was true. it's almost impossible to quit a meth or heroin addiction after a year of doing it. the recidivism rate for meth is like 95%
Well for me personally, I have incredible amount of difficulty maintaining interest in things so it's easy for me to lose care or desire for whatever it may be. And I know those drugs are a lot harsher, but I was initially refering to simple things like cigarettes or for some people, even coffee.
