A new study led by Swansea University has found a link between finger length and the likelihood of developing severe Covid-19.
The study, led by Professor John Manning, examines the link between testosterone and Covid-19 severity more closely by looking at how long your fingers are.
In general, men have longer ring fingers than index fingers due to higher levels of prenatal testosterone, whereas women have the opposite as a result of higher levels of oestrogen. Another indicator of low testosterone in puberty in particular is a shorter pinky or little finger relative to the middle finger.
