At the risk of exposing my spelling and grammar, life experience is a very subjective phenomenon and does not necessarily go with age.
No doubt there are plenty of people in their 30s/ 40s who live with their parents and sit indoors all night playing online games.
Equally there will be people in their teens/ 20s who will have spent time in cadet forces, completed their DofE awards and volunteer within their community.
Life experience can only be quantified on a case by case basis and should not be generalised. I can only hope that recruitment professionals understand this.
