He opposed the popular notion of German racial superiority. His findings about the parasitic disease trichinosis led to a successful 10-year campaign to establish compulsory meat inspection in Germany. He kept to facts and required this from other people. I dentification of individuals at risk for early myocardial infarction may be as close as your fingertips A high-ratio of the length of the index finger to the length of the ring finger is associated with early acute MI, at least in men. This trait is present and readily assessable even in early childhood according to Dr John Manning, speaking at the World Organization of Family Doctors in Durban, South Africa.
Good data shows that the finger-length ratio is fixed for life in utero.
Men with a below average finger length ratio typically have their first MI at an advanced age, if they have one at all. The ratio of the length of the 2nd finger to the 4th digit is a trait that varies by gender and ethnicity. The mean ratio is lower in men than women. Whether finger-length ratio predicts risk of early MI in women isn't yet known. The right hand should be used since it seems to correlate better with MI risk even in left-handed people.
