In the near future, the average human lifespan could extend beyond 80 years to reach 110 or 120. Scientists have identified several "anti-aging" strategies that boost the lifespans of mice, including the manipulation of certain genes and a reduction in the animals' caloric intake. Trials with the diabetes drug metformin, which increases the amount of oxygen released into cells, have also shown promise, boosting the lifespan of mice by nearly 40%. (Human trials are scheduled for winter 2016.) Additionally, a February 2016 study concluded that removing senescent cells from mice increased their lifespans by more than 20%.
