Saturn in Taurus takes risks only for what is worth it: in a couple, they take chances to protect or grow what they consider valuable. They watch what keeps or increases its value and what may lose it.
They need a why and a what-for. Even when they practice an activity that seems dangerous, they try to know the conditions and anticipate the unexpected before acting. That preparation can give them confidence, although calculating a risk is not the same as eliminating it.
They prefer to feel that the effort has a concrete use and a basis on which to decide.
