List of Rules & Duties for being 48

I've been enjoying reading the writings of the prolific Maria Popvov, and happened upon her writings on Susan Sontag Rules for being 24.

I thought I'd come us with a few rules for being 48:

• Eat Les
• Drink less
• Do core and/or strength training twice a week
• Don't complain - Don't explain
• Be direct and firm with 'getting to be adult' children. Support and Love them. Provide guidance, but let them choose
• Spend more time fostering old and new hobbies with bride
• Listen more. Criticize Less.
