Stressful Dates for the 40s, 50s, and 80s Age Groups are related to Mars making adverse aspects to Neptune by transit.
Mars is making an unusually long station in the sign of Libra from 7th Dec 2013 till 25th July 2014.
This means that anyone who was born with Neptune in Libra (the 1940s and 50s age group) and Neptune in Capricorn (1980s age group) will be getting adverse aspects from transiting Mars for most of this period.
