My immediate family is in poor shape. Health troubles across almost everyone along with varying degrees of emotional stress.
One tries to responsibly pursue “restorative” activities that give you back energy like meditation, light exercise or movement, and if you happen to be lucky like we are some supplemental oxygen.
