Prompt
In model definitions, numeric parameter values can be specified as continuous ranges rather than explicit lists of every integer. Base models often try writing custom Python list comprehensions or regular expressions. Write the parameter line syntax for defining a numeric range parameter named `Age` covering values from 18 to 65.
