>>62163160>>alcoholThis is dumb, you're probably addicted to being drunk which is bad for you in multiple ways. Stick to a glass/beer a day or just remove it cuz it's just empty calories and it's gonna make you fat and dumb.
>>nicotineDepends on how you're getting it. Nicotine by itself is not much different from something like caffeine, it even improves your mental state and reaction times by a good 30-50ms. If you're smoking then you should worry about literally everything elsle that's not nicotine but if you're just chewing gum or using patches then as long as you don't use a retarded amount you should be fine.
>>caffeineAgain, it's just an stimulant, don't overdo it and depend on it just to function, the worst thing it can do is fuck up your sleep schedule and give you extra anxiety.
>>masturbationIt just makes you release a lot of dopamine which leaves you uniwilling to do literally anything else.
>>vtubersIt doesn't hurt you as long as you don't give them money and become a delusional simp who believes they're your gf.
>>a dogshit mobile LOL copy game, seriously i have over 5000 hours in this gameThis is just a case of shit taste, if you're gonna spend a lot of time in a game at least get into something that's actually genuinely good.
>>sniffing gasolineI have no idea what this does to you, but I'm gonna assume it's a milder version of sniffing paint. Definitely not good for your brain in the short and long term.
