As far as advice goes, I’m not ever going to be one to tell you what you should or shouldn’t do upon reaching a certain age. As far as I’m concerned, you should wear whatever makes you happy and comfortable. Whether it’s leggings, hoop earrings or hot pants, I don’t care. You should eat what you feel like, workout as often as it suits your fancy, and use the oxford comma or not according to your taste.
… Oh, wait. I will probably judge you on the comma use, but carry on with the other stuff.
But there is something I think anyone over a certain age needs to come to grips with: Selfies.
You guys. There is possibly no more distinct line of demarcation between the old and the young than the ability (or lack thereof) to take a decent self-portrait with one’s personal electronic device.
… Except for maybe the TV remote thing. But in the interest of being concise, we’re going to focus on the art of the selfie here.
