When you open a jpeg, most of the information from the original tiff

I must interject here...to see if I have been misunderstanding a concept.
It has been my understanding that if you only open a jpeg for viewing
and close it again, there will be NO degradation to the original image.
That it's only manipulating a jpeg image and *then* saving it that
creates small losses which accumulate and soon become noticeable.
IOW, don't manipulate a jpeg and you won't suffer image degradation.
True or not true?
