One thing I still do is trying to shift into seventh
It does no harm but I always feel stupid when I do it.
You find at some point the whole thing pivots and you make mistakes
because everything has become automatic so your attention begins to switch off a bit, talking to yourself and thinking through your day then suddenly the car in front is emergency stopping or a deer runs out and you were running on autopilot.
You will deal with it okay but your heart rate will be up.
Leaving the side stand down used to be a favorite but these days they have cutout switches so you stall instead.
ps Try riding an old British bike, that will give you a co-ordination crisis for sure (right foot shifter one up three down )
