I have a giant oak tree next to my house, perfectly positioned so that my house is in direct sunlight in the morning but completely shaded by the tree from noon onwards, so even when it’s 100°F outside my house doesn’t get above the low 80s. I love that tree - except for right now when I have to rake the fucking yard.
I used to drink five 24 oz. cups of coffee a day - which is about one gallon - including the last one right before I went to bed, and I never had any trouble sleeping. Your body adjusts to all kinds of ridiculous shit.
