What Glen said...
Disregard the likes of pilotchute - they are the ones with an overinflated sense of entitlement who think being older automatically makes them better than their professional peers.
I've experienced him firsthand
Just because you might be older than those who started young, be mindful that, especially in aviation, there is no substitute for experience and good mentoring.
Go for it, but speak to people in the job face to face and research all aspects. Use your previous skills to assist your development in the new profession and be humble.
