Conditioning does not equal "habit". You can train a lot of things to the level of muscle memory (like I always check seat belts before moving and avoid taking them off, or how I mentally recall coordinated turns even when turning while walking), but it's a completely different set of behaviours - or at least totally different difficulty level - when it comes to "habits" that take longer time and aren't linked to directly executed skills - think like making a habit of training every few days to get more fit, or even habit of checking email at the start of work day.
