Yesterday, I had to dig out the report from a colonoscopy I had six years ago. I had expected my doctor to have it, but they’d changed computer systems and no longer had the information. Therefore, he wanted my copy. I wished I’d taken a photo of it, so I could have pulled it up on my phone.
Likewise, people often write down names, email addresses, appointment times, or other important bits of info on cards or Post-It notes. We sometimes write notes for ourselves on scraps of paper during phone calls. In all these cases, make a habit of snapping a picture. It’s usually easier to find the photo (especially if you use a service like Google Photos that has search functions.) If you lose the original, it won’t matter.
