If you were wondering about the segulah of davening 40 days straight, that segulah has just been upped and outdone. 40 days in a row is now passe. The Kupat Ho'Ir of Bnei Brak is now advertising that they will say the entire tehillim for you (and for your donation) for 40 days and 40 nights in a row!
Where does this go from here? 40 mornings, 40 afternoons and 40 nights? 40 times each day for 40 days? What other multiples of 40 can you come up with that they can use for targeting your donations?
