** Teacher and Professor (increases exp growth rate for non-combatants/ or slowly increases non-combatant based skills for non-moving allies in same tile with at least 1 non-combatant class) + (slightly better non-combatant stats for royals who come of age in this tile) + (slight knowledge/ turn increase)
*Nurse (+1 HP/ turn for units in a city)
*all medical bonuses refer to units In SAME TILE of course
*Medic (+1 HP/ turn for units ... anywhere or within borders)
