Greetings friend,
You're very correct. Experience isn't solely determined by age or circumstances as it comes from time, exposure, and practice. Just because someone is old doesn't mean they automatically have experience in everything. It's all about learning, being exposed to different things, and actively practicing them. Experience is like encountering, practicing, being familiar with, and becoming proficient in something. And until you actually have those experiences, you won't truly understand them, regardless of your age or circumstances. This is why it is important for us to keep learning and gaining new experiences in life.
