Be my guest, Hoppy......
You may "choose" to use interested and disinterested......
Or motivated and unmotivated......
Or concerned and unconcerned......
Or brave and cowardly......
Or tall and short......
Rather than liberal and conservative OR conservative and liberal.
But I prefer painting any King's English portrait I postulate with carefully chosen words that most accurately convey my intended meaning.
Thus......
I did not begin my last missive on this thread with any query to determine if others had observed that most human beings become disinterested, or unmotivated, or unconcerned, or cowardly, or short...... As they live out the final years and decades of their brief existence on our tiny planet.
And BTW......
It is my personal opinion (via experience) that most aged human beings are no more disinterested, unmotivated, unconcerned, cowardly or short...... Than any particular group of younger human beings.
Cheers.
