VHS tape is magnetic and the video signal is encoded onto the magnetic video tape. Over time, the magnetic storage of the tape weakens and the information is lost. A tape after 20 years loses some of the information compared to a newly recorded tape. To prevent the loss of this information, it should be converted to DVD or a flash drive that can be stored on other media. This will preserve the contents of what was originally on the video tape. Video conversion is your best option to save your memories.
