There is no question here, only a statement. 

What kind of answer do you expect? 

Essentially -- I guess -- you have to see how much difference 
the treatment of the variable specified makes. This can be informal 
as well as formal in terms of looking at whether the model 
appears to perform better in one case than the other, including 
how sensitive coefficients of the _other_ variables are. 

In other situations, there is sometimes an argument for 
including a variable both as continuous and as discrete. 
But experts would need more information to comment further.
