The other advantage is clarity when one looks back at a program. 

9=5*6

Or

Amount=cost*quantity

Now which is clearer?

I started using the field names a long time ago. However one can not so this if the field(s) are associated. 

As for long variables, I use the format of capitalizing the first letter and the first letter of the second syllable 
QuantityShipped

Many My field names have an underscore joining it's parts
Qty_ord.  qty_shipped
