Actually, from what I understand, these are calculated life spans. They take the percentage of people dying at each age *today*, and integrate that information to calculate a predicted lifespan. It is how old you would live to be if you were born today and your chances of dying at every age remain exactly the same as they are today.
It is likely that lifespans will increase, although there are some threats to mortality in the near future, such as antibiotic resistant bacteria, and harmful organisms being spread by global travel.
