Activities unsuited for a castaway

As a sole survivor of a pandemic, steer away from these games and activities:

• Halma (board game invented ~1883 by the American plastic surgeon at Harvard Medical School, George Howard Monks). One can debate whether Halma is a thrilling game - it is definitely extremely boring when played alone.
• Conga line dancing (Cuban carnival march, popular in the USA in the 1930s. The dancers form a long, processing line. It has three shuffle steps on the beat, followed by a kick that is slightly ahead of the fourth beat). It is heavily debatable that “the conga” is an enjoyable exercise at all… but have you ever tried this on your own?
• Tennis. For obvious reasons, it is better to concentrate on playing squash.
• Participating in panel discussions. Very hard to do on your own – although even in our heavily populated world, many people (generally referred to as “eccentrics” or "weirdos") seem to prefer heated political debates with themselves, instead of with neighbors or family.
• Bungee jumping (an activity that involves jumping from a tall structure while connected to a large elastic cord). Only makes sense with people watching you wet your pants.
• Paintball (an activity involving players to compete & eliminate opponents by hitting them with capsules containing paint from a device called a paintball marker). The usefulness of this game is disputed. In a post-pandemic world, one would hopefully ENJOY meeting another people, not shooting them.
