One of the consequences of developments in medical care is that the longevity has risen across the globe. I believe its advantages are greater than its disadvantages.
On the one hand, the increase in lifespan of people means that more lives are being saved due to innovations in healthcare. Furthermore, this also means that many diseases are being eradicated, which is overall a good achievement. As humans begin their quest to live long, they are also evolving as a society at a much greater pace. How is that? If people live more – especially geniuses who can sustain their intelligence – they can contribute more to humanity. It can also be taken into account that younger people will get more time to spend with elders, and benefit from their experience.
On the other hand, a rise in life expectancy will burden taxpayers as this will warrant more welfare schemes for the elderly. In addition to this, there are people who would rather their lives end peacefully than suffer chronic pain or diseases that is common in old age. Consequentlly, no matter how long our lives extend, all humans are subject to senility at one point or the other. While modern advances in science can render the body more usable, there has been little improvement in the field of mental health of aged people.
In conclusion, the duration of life has indeed increased in recent years, and it certainly has some disadvantages. Though in my opinion, its benefits overshadow its harms. Moreover, further researches and breakthroughs have the potential to offset those few disadvantages.
