Actually, a bajillion is not a real number so I will round this up to a billion, which is the closest word and number to a "bajillion". An average nosebleed lasts 5 to 10 minutes, so I will average this to 7 and a half minutes. A billion nosebleeds would last about seven and a half billion minutes, which is 14,262 years, 7 months, and 20 days. You are 14 years old, so the most amount of times you could have had a nosebleed is 981,792. However, you would lose about 45 ml of blood every nosebleed. However, an average newborn only has 272 ml of blood. If your nose were constantly bleeding, you would have died after 22.5 minutes since you would have lost ~35% of your blood by then, which is enough to cause an infant to go into shock or die from blood loss.
