switch case and inequalities

So, say I wanted to disp('that's impossible') if a user enters an age over 150 or less than 0?
How could I do this for a switch case if I can't use inequalities?
I know that between 0 and 150, I could use case num2cell(0:150), but if I don't have bounds for less than zero & over 150, how could I use num2cell?

        It is possible with switch:
age = 200;
switch true
  case age>150
    disp('that''s impossible!')
  case age<0
    disp('not born yet!')
end
But using if and elseif might be clearer.

        switch Age
 case num2cell(0:150)
  disp('Valid')
 otherwise
  disp('that''s impossible')
end

				switch Age
 case num2cell(0:150)
  disp('Valid')
 otherwise
  if(Age<0)
   disp('that''s impossible')
  else
   disp('that''s unlikely')
  end
end
Is there a reason you want to use a switch? If Age is manual input by a user, I think "case num2cell(0:150)' will only match with integers between 0 and 150, so if a user has the ability to input 25.75 for Age, nothing will happen with this logic.
