The "999 years" are a cumulative total of the years of marriage represented between all the Abundant Wives I've interviewed for the book, based on their anniversary and the date of their interview. This complete series of the audios is just over 43 total hours of audio - that's over 23 years of marriage wisdom inside of each single hour of content!! Talk about potency - WOW! Not every single audio interview is released in this series, but the content is in the written book so you'll want to grab a copy!
