By making use of the concept of natural time, a simple model is proposed which exhibits the 1/fa behavior with a close to unity. The properties of the model are compared to those of the Seismic Electric Signals (SES) activities that have been found to obey the ubiquitous 1/fa behavior with a ≈ 1. This comparison, which is made by using the most recent SES data, reveals certain similarities, but the following important difference is found: The model suggests that the entropy S- under time reversal becomes larger compared to the entropy S in forward time, thus disagreeing with the experimental SES results which show that S may be either smaller or larger than S-. This might be due to the fact that SES activities exhibit \em critical dynamics, while the model cannot capture all the characteristics of such dynamics.
