c
Apps and apples. C follows you until you’re 100 years old. Whether it’s a vitamin in your smoothie or part of the apps on your laptop and smartphone, C is part of your whole life. C forms the basis of many programming languages, including C++ and Java. An app against boredom and an apple (or orange) a day to keep the doctor away. With these, you should be able to reach your 100th birthday with a smile on your face! How do you keep your engines running?
