Javascript - function with objects

I'm trying to write a function, but it's doing the opposite of what I'd like.

Write a function that determines whether a user is old and tall enough to ride a roller coaster. The function should take an object as a parameter. If the object's age property is greater than or equal to 7 and the height property is greater than or equal to 42, return true. Otherwise, return false

const rollerCoaster = (object) => {
  if (object.age >= 7 && object.height >= 42) {
      return true
  } else {
      return false
  }
}

console.log(rollerCoaster(55, 55));

This is returning false, we want it to return true. What am I missing?
