I'm like I can either be in 4th gear or in neutral. I don't know other gears.

'Inertia' can be removed by gulping a few rounds of country beer. 😜 This is my way. Sometimes I remove it with a Marlboro Red, only once or twice in a month. Sometimes it just takes a cup of coffee or tea.

However most of the times a walk on the terrace or at some wilderness help me shed my inertia.
