I have embraced the twilight, plugged in but I carry the tools to the wood. I feel neither compomised or abused.
Tim if you should pickup a Mafell mortiser again, my suggestion is that the carpenter must dominate the tool and the top of the workpiece should be knee high or lower. I'll be sixty this summer, still working and the back is fine. I nevertheless do have other medical/wellbeing issues but not tool related.
