Many souls in the medical field propagate the view that our average lifespan as humans has been increasing, thanks to advances in science, technology, and medicine.
Take for example this projection by the United Nations, for the United States (U.S.).

Looking at the graph above, we see that the average life expectancy was 68 years in 1950, is 79 currently, and is expected to go up to 89 by the year 2100.
However, I beg to differ, because the data does not take into account 2 major factors. One is, contraception, which prevents life from taking root, and the other is abortion, which prevents a soul from taking birth despite having got a start in a mother’s womb.
In this post, I’m not looking to get into a discussion about contraception or abortion itself, I just want to point out that with modern science and medical advances, the average human lifespan has actually decreased, not increased.
Here is a rough calculation to illustrate my point.
The current life expectancy in the US is approximately 79 years. The average human in the U.S. is expected to live 79 years today. There are about 334 Million humans in the US today, so collectively we are expecting to see about 26,386 million “human years” of life lived.
From 1973 to 2018, over 62 million babies were aborted by surgical means, according to the American Life League. So, if these babies had not been aborted, they would be still alive, or the oldest babies, from 1973, would be about 48 years of age now. Of course, babies were being aborted before 1973 also, but I am not in possession of those statistics.
However, from the same source, when we include the chemical abortions (the pill method), from 1965 to 2009, over 610 million abortions have been conducted. In 1965 the average life expectancy in the U.S. was 70 years. In other words, on average, everyone born in 1965 is expected to be still alive today.
Each of these babies, if given a chance at life, could have expected to live a minimum of more than zero years… whatever the lifespan would have been, it would have been unlikely to be zero years for all the babies.
Roughly, taking into account all the humans who died before birth, or reaching the age of zero, we are looking at a U.S. population of 334 Million (current) + 610 million (killed by contraception or abortion). A total of 943 Million.
If we divide the total of 26,386 million human years by 943 million humans, we get an actual average life expectancy of about 28 years. The 79 years number is just for someone who somehow made it past the risk of murder before birth! So it is a false statistic, a classic statistical trick (change your denominator) to make a number look more rosy.
In other words, when we take into account the actual count of souls who got a start in a human mother’s womb, the current life expectancy is actually 28 years only.
My calculations are not exact, they are just rough back-of-the-envelope numbers. But they are directionally correct. And I haven’t even calculated a model for non-chemical contraception, using physical methods like condoms and so on. The actual life expectancy numbers will be much lower, taking those factors into account.

In the purport, the disciples of His Divine Grace A. C. Bhaktivedanta Swami Prabhupada write:
Because of all these self-destructive practices and the powerful influence of time, the average life span (āyur) is decreasing. Modern scientists, seeking to gain credibility among the mass of people, often publish statistics supposedly showing that science has increased the average duration of life. But these statistics do not take into account the number of people killed through the cruel practice of abortion. When we figure aborted children into the life expectancy of the total population, we find that the average duration of life has not at all increased in the Age of Kali but is rather decreasing drastically.

This should be noted and pointed out to the scientists, doctors, and others arguing that our average lifespans are actually decreasing.
