Alex has gotten into playing Halo with me, so when Halo 3 came out he really, really wanted me to get a copy. I know it is rated "M", but Halo isn't really that bad. There are lots of World War II games where you shoot people and they are only rated "T". In Halo, you just blow up monsters, so I am not sure why it has the "M" rating. Anyway, we like to play cooperatively so we can work together to save the world. The new one is very good for cooperative play and has lots of funny weapons that crack Alex up. There is a gravity hammer that he thinks is pretty funny. After he caught on as to which trigger was for grenades and stopped accidentally blowing me up, we worked well as a team and managed to finish the game on the "Normal" level. I think that Bungie did a great job on Halo 3. Alex still needs practice on his Warthog skills, but he's got the sword and hammer down, and is improving with the plasma cannon. Always good skills for a kid who goes to public school. :-)
For Christmas my wife gave me a Netatmo weather station because I am a home weather station nerd. The Netatmo is very cool, but it has an unexpected feature: it measures indoor Carbon Dioxide (CO2) levels. As soon as I set it up, the Netatmo began to alert that our indoor CO2 was at an unsafe level. The notes said that outdoor CO2 is usually around 400 ppm, and numbers above 1500 ppm could be unhealthy. On that first day, my house was at around 1300 ppm. Prior to that, I never gave indoor CO2 levels a thought. I began to do some research and discovered high levels of CO2 can cause symptoms such as fatigue, headache, breathing difficulties, strained eyes and itchy skin. My family does have all of these issues, especially on the weekends when we are home all day, but I never connected that to indoor air quality. Previously, I installed a Nest thermostat . The Nest is very smart and saves energy by learning your habits and programming itself. Unfortunately, it is so efficient, that t
