Humourous: Humorous is a fine tone for toasting at your friend's wedding, but not so much for the reading of someone's last will and testament. When we talk about humor, we're usually talking about something funny. But originally the word humorous had to do with the body's humors, or moods.
Loving: feeling or showing love or great care
Insincere: not expressing genuine feelings.
unhealthy: not having or showing good health.
