TXgolfer - you are the ONLY person (out of thousands) I know who's said that it wasn't tiring/stressful etc speechreading.
Maybe it's different if you're LD, but for those of us who were born with hearing loss, especially with hearing loss that "got worse" over time, it IS exhausting. This isn't opinion, it's been scientifically proven that even the most proficient and natural speechreaders have to work mentally harder to understand than their hearing peers.
If speechreading is relaxing and passive for you (like listening is for hearing people) then you are a rare exception, and most certainly NOT the "norm".
