Storage wasn't needed here.

tiny nit: why change this?
In general, I think using storage references is usually (there are some exceptions) preferable (gas-wise) to copying the entire struct to memory because you may not actually need to SLOAD every element of the struct and you may end up using less memory overall by avoiding the copy. Does that make sense?
This is just a demo contract, so it's not super important, just wanted to make a note of it!
