32bit-64bit

I heard that using shorts on 32bit system is just more inefficient than using ints. Is this the same for ints on a 64bit system?

Python recently(?) basically merged ints with long and has basically a single datatype long, right? If you are sure that your app. will only run on 64bit then, is it even conceivable (potentially a good idea) to use long for everything in Java?
