I'm supprised that no one mentioned COMFORT! I know for me, if I'm not sitting (or standing) in a comfortable position, scrolling becomes an effort. Every thing seems to go easier and better if your feet (or other parts of your body) are not in pain.
When my back starts to ache, it is harder and harder to make nice cuts in the wood. So, I take five, grab a bottle of water, stroll around the shop or house or yard for five minutes or so and when I get back to the saw "Things go better with a rest"
(I think Coke stole my saying
