[Ethics of a long life]

The increase in average life expectancy that has taken place since 1850 and is continuing globally to the present day can be seen as a major achievement of civilization. However, many are skeptical about demographic change and the continuing trend of increasing life expectancy beyond current limits. The reasons for this lie in deeply rooted cultural attitudes towards old age and the elderly.This article counters these attitudes with principles for a long life that emphasize the benefits of the first revolution of life extension. Research should be promoted that can ensure this gain and holds out the prospect of a further extension of the human lifespan as a result of a second revolution.
