That image made me think about all those fancy 'thicc' mechanical keyboard on Youtube. My wrist hurt just seeing the video. Low profile keyboard FTW!

If you had that particular type of pain, it will become "obvious". You'll feel the pain of maintaining the wrist flat, and the pain will be less in that posture.

Same with my back pain and lumbar support. Once the lumbar support gave me relief, I could easily tell which chairs/couches were terrible for the back as the bad ones would give instant pain.
