Yes, excactly. And in fact im interested in heterogenous effects of 
income on BMI growth looking at different sub-samples in the data.

Still, im not sure if thats the best way to model it as I have a hard 
time to interpret the logIncome coefficient ( I know what it is, but 
find it hard to get an idea of what it actually means)
