Most people log only those activities that are above-and-beyond their usual, such as 60-minutes of shoveling snow or 3 hours of dancing.  The activity level you set in your profile should cover your usual activity.  For instance, if you usually walk about 30 minutes a day and perform light household chores, you could choose "Light Activity" and let that be good enough.  When setting your activity level, consider what you do over the course of a week.  Your "activities of daily living" (sleeping, washing, etc.) and the calories your body burns to stay alive (heartbeat, temperature, etc.) are already included in the activity level you have set.
