Today, I've made a :python: program, inspired by PracticePython's 1st challenge (bit.ly/3bbsodl), and hosted on :replit:, which predicts at which ages users reach their peaks in life (repl.it/@alialiwa2005/When-Youll-Reach-Some-of-Lifes-AverageCommon-Peak-Ages). This program is opensource, under an MIT license; so feel free to fork & hack!
