Similiar to Xbox Live, Life Achievements are various tasks and challenges one can accomplish in real life such as successfully evading the police, urinating on a moving vehicle, or throwing an epic party. Achievements accumulate Lifepoints (LP) based on the difficulty of the task that adds to a persons Lifescore. Life Achievements, and their corresponding point values, can be found from various sources on the internet.
Life Achievements:

Follow Me If You Want To Live - Survive a natural disaster using only your wits and cunning. 100 pts

That Cant Be Healthy - Stay indoors for 3 weeks straight. 50 pts

Nice Hussle Out There - Be the reason that your team lost "the big game". 75 pts
