Best Answer

The very large increase in average life expectancy in the 20th century is due to four major factors, and two minor ones. These factors are (from most important to least):

  1. Clean drinking water
  2. Universal sewage and high levels of personal hygiene
  3. Better nutrition, particularly at the pre-natal, infant, and childhood levels
  4. Vaccination against most epidemic diseases
  5. Higher access to lifesaving trauma care
  6. Improved drugs

#1 and #2 are by far the biggest contributors to increased life expectancy. Besides vaccines, about the only drugs that has made a major contribution to life expectancy are antibiotics.

What is the life expectancy of a patient with Marfan syndrome?

Recent advances in Marfan syndrome treatment have prolonged the life expectancy of patients considerably. Changes in how the syndrome is treated, including medication, surgical interventions, and monitoring for complications of the syndrome (eg, aneurysms), are all responsible for the increase in life expectancy. The prolongation in life expectancy can be seen by taking a look at statistics from 1972, in which the life expectancy was 32 years, and from 1996, where patients with Marfan syndrome had a life expectancy of 61 years.
