Ooh, take care of those lungs, Lynn. Not getting new ones on the next milestone birthday...
Deborah, I find that when I bring my mixed succulent containers indoors there's a noticeable elongating of stems of the sedum and leaves appear further apart. I take care of this out-of-shape look in the spring by pruning back to encourage branching. Also the rosettes of echeveria will get a little out of shape by slight elongating of the center where the growth comes from.
Definitely helps if these succulents can overwinter near bright/sunny window exposures.
