A low darwinian factor is defined as having genes or an attitude that may guide one's life activities to be excluded from subsequent generation's gene pool for one reason or another. Those that partake of LDF activities are assumed to have an LDF.
For example, homosexual men tend toward a low darwinian factor. Other examples of low darwinian factors can be found observing those who like tree skiing, ski football, riding motorcycles without a helmet, etc... This is not to say someone with an LDF is not a nice, good or talented person. Rather that they may not live to reproduce if they keep up their ways and/or lifestyles.
