The fact is that the maximum human lifespan — a concept often confused with "life expectancy" — has remained more or less the same for thousands of years. The idea that our ancestors routinely died young (say, at age 40) has no basis in scientific fact."
"If a couple has two children and one of them dies in childbirth while the other lives to be 90, stating that on average the couple's children lived to be 45 is statistically accurate but meaningless."

"As researchers Judith Rowbotham, now at the University of Plymouth, and Paul Clayton, of Oxford Brookes University, write, “once the dangerous childhood years were passed… life expectancy in the mid-Victorian period was not markedly different from what it is today”. A five-year-old girl would live to 73; a boy, to 75."
"Looking at dental wear on the skeletons of Anglo-Saxons buried about 1,500 years ago, they found that of 174 skeletons, the majority belonged to people who were under 65 – but there also were 16 people who died between 65 and 74 years old and nine who reached at least 75 years of age."

During the industrial revolution poverty and disease meant the average life span in England in 1841 for newborn boy was expected to live to 40.2. whereas a baby girl was expected to live to 42.2.
This is according to official records, although the average age was even lower in some industrial cities such as Liverpool where the average male had a life expectancy of 27 years at this time.
However improvements in nutrition, hygiene, housing, sanitation, control of infectious diseases and other public health measures have reduced mortality rates, increasing life expectancy to 56 years for males and 59 years for females by 1920.
By 2019, life expectancy at birth in England had increased to 79.9 years for males and 83.6 years for females.
In terms of Covid it might have some impact, however this may be just short term rather than a long term feature in terms of life expectancy in most countries.
