You're in your carefree 20s, living life to the fullest and staying out until 4 am. A few hours later, you're completely fresh, starting your shift at the coffee house. Hangovers do not exist, you have a ton of friends and can eat a whole pizza without any consequences at all. Suddenly, you're 30. The only parties you're going to now are your child's birthdays. Half an hour of sleep missed means you'll be cranky, the best present for you is a now a cooking pan, and dad jokes are the most hilarious jokes ever. Do any of these life changes sound familiar?
