Eating too much, sitting for too long, drinking too much, playing on their phones all day long... It sounds like nobody's life can be as unhealthy as that, but when we look at our daily life, everyone can be concerned and it even seems that this looks like most people's daily life. After drinking for a whole night, some people get up the next morning with a serious headache which usually lasts for many hours. They promise to quit alcohol and do exercise to have a healthy life, but a call shortly before getting off work destroys everything. Their friends invite them to hang out and they don't refuse. After enjoying another "amazing night", they show up at work the next day feeling like they will die! All they can do is just playing on their phone and sit at their desk and wait for the clock to ring again but maybe another call will change everything again! In that case, we should learn how to refuse friends' invitation, then stand up and walk around our tables and stretch our arms. Even if you just do a little exercise, it's still better than doing nothing. We live in such a magic world, we can't leave without our phones, offices and entertainments. Nature is just out there, but it's really far from us! Maybe we get a slight pain on our back after sitting in our offices for a long time, but we might end up one day in a hospital due to a serious back pain! Take care yourselves, my friends!
