I ate a green pepper without anything else and it was decently spicy. I can handle that and wasabi. I'm not sure what really spicy is though. Not a professional of spicy things.
Yes, since half of my family are Guyanese:P We always cook extra spicy curries and I can eat it all whilst my dad is sweating trying to finish his plate‼ I can even eat wasabi peas=O
Not really. I get the worst cramps ever if I have anything too spicy. Though I upendo jalopeno and monterey jack cheese taquitos, but they cause problems as well.
i eat a bag of flaming cheetos a day... and i have always loved putting hot sauce on my food... yeah, i can take the heat... to a degree (see what i did there ;3 XD)... if it's too Extremely hot, then no.
