I often wonder why I take selfies when I am hiking and in the gym. I realized why yesterday while hiking. It is because of battery life of my phone. Whenever I take out my phone, I go for facebook. I stop myself from logging in because every time I log in, the battery life of my phone drops down by 10%. So if I have less than 50%, I do not go to facebook. I stop myself. Whenever I stop myself, I click on the camera then take a selfie for some reason lol.
By the way, I just turned 24 a month ago. So I look a little bit older now.
