A new scientific study indicated that the differences in the length of the fingers between the left and right hand may hold the answer to the extent to which a person is affected by Covid disease.
Men and the elderly are more susceptible to serious infection with Covid, which is why experts believe that the decline in the level of testosterone with age may be linked to this.
Information about testosterone is believed to be preserved in finger length ratios.
John Manning, a professor at Swansea University, hopes that his work with colleagues in Poland will help identify patients at risk of serious infection with Covid.
In men, the pinky and ring fingers are longer, compared to women, in relation to the middle and index fingers.
Numerical ancestry expert Professor Manning, in collaboration with colleagues from the Medical University of Lodz in Poland, published a research paper stating that there is a link between differences in left-right numerical ratios and hospitalization due to COVID-19.
“It is hoped that understanding these associations will lead to an increase in our ability to accurately identify individuals at risk,” he said.
These findings follow research published this year on the severity of Covid disease and its relationship to low testosterone and high estrogen levels in both men and women.
“Our research helps advance understanding of severe COVID-19 cases,” Manning said. “Hospital admission is more common among the elderly and men, but there are many elderly men who have had mild symptoms of COVID-19.”
And vice versa, young men and women are not guaranteed to have mild symptoms of the disease.
He continued, “Our research may help identify those people who are more likely to be hospitalized among different age groups.
