- mechanical keys - reduced movement;
- buy a custom build - have industrial build quality;
- barely any movement - good blood flow;
- avoid rolling - type fast;
- concave keyboards - tenting;
- fewer keys - minimal;
- uniformly shaped keys - touch typing feedback;
- keep hands on the keyboard - move pointer precisely;
- custom layout - conventional shortcuts.

I noticed when I exercise I can sit comfortably on a firm basic stool, and when I don't I become a princess on a pea.
How about we start with the basics? Good posture, correct hand positions, monitor at the right level, exercise, nutrition. Then an IBM Model M would suffice.
