Good 40th birthday ideas for men include parties based on superheroes, sports, guys' movies, barbecue or daring deeds. Whatever theme is chosen, it is important to gather all necessary party supplies and to notify guests via invitation. The invitation can include special instructions, such as the party dress code.
A superhero-themed party taps into a man's inner child by focusing on a favorite superhero in which he has maintained interest. Guests bring vintage toys related to the chosen superhero, and the host chooses party favors that match the theme. As part of the event, the host can either rent out a local theater or show relevant superhero movies at his own house. A similar idea is to rent out a local theater and host a party themed around the guest of honor's favorite action movie hero.
Sports provide a solid theme for male birthdays. Grilling food and playing sports with friends at a local park can be the basis of the party, or the hose can choose to throw a party at a sports stadium and attempt to wish the guest of honor happy birthday on the large screen by contacting the sporting team ahead of time.
Barbecue makes for a memorable 40th birthday party theme. The host grills the guests' favorite foods while they bring side dishes and share amusing stories about the guest of honor. A final theme idea is to take the guest of honor skydiving, bungie jumping or on another daring activity.
