How far can you safely reach?

I bought a fruit juice today, freshly squeezed in a big bench top machine.

The attendant had to reach a long way to put the fruit in.
Her arm was at full stretch.

I watched her a few times, and then offered a suggestion.

“Pull the machine closer and rotate it a little - so the ‘fruit’ hole is no further away than the cup that collects the juice."

The aim - much shorter arm movements.

She asked me “are you a chiropractor?” We both laughed as I explained a little about Alexander Technique.

Most people simply don't notice how their work setup affects their movements or posture, even if they suffer pain.
