If you are in the arctic on a dog sled or climing the K2, it's perfect!
how do you get in that many? i struggle with 3500+ daily
If ur bulking, then it's pretty normal
That's pussy numbers 3 big macs, large coke, large fries, apple pie and caramel sundae
depends on what does those calories consist of, if you ate mainly fast or junk food then that is a horrible experience for your organizm, otherwise if you ate healthy, home cooked food then you just exceeded your daily calorie intake, so your body will consume what it needs and will dump the rest when its digested
Of course no, just drink a cup of oil before sleeping
