Quick Answer. The bull shark life cycle starts when a mother gives birth to anywhere between one and 13 babies per litter. Its gestation period lasts 10 to 11 months, according to Wildscreen Arkive, and they generally give birth between late spring and early summer. They live in estuaries, river mouths and sometimes freshwater lakes.
No one knows for sure, but because bull markets age in what you might call dog years, if it were a human it would be very, very, very old. The average American lifespan, despite a slight decline recently, is about 79 years, or 948 months. The average age of a bull market, meanwhile, is 57 months. So, if you assume that every bull-market year is equivalent to about 16.6 human years (948 months divided by 57 months), this eight-year-old bull market is actually 133 years old. (The oldest person on Earth is currently 117.)
