You can provide them an example of some members who are successful and have more than 50 years.
I think that I can be the best example to my potential members, because I'm almost 50 years old and I’m very happy and pleased to have the opportunity to do this job. The fact is that the older population have more free time than younger people, so they can spend much more time doing this job. Beside that, SFI offers a lot ways to profit to potential members who belong to this population.
