Welcome at HAFA.

The international survey is an opportunity to reflect about your health goals for the summer as well as your previous dietary and exercise habits.

We invite you to fill in a 15-minute online questionnaire. Ten Amazon vouchers (worth 15 Euros each) will be raffled among all participants.

The HAFA-team wishes you lots of fun,
