I am about to start my CPL(H) including

Certified Flight Instructor - Instrument

I guess the difference is that the "older" guys have their head switched on a bit more with life experiences ( not saying younger guys dont have them too)
As they generally tend to have a few more & tend to be a little more level headed.
Like myself , many other older pilots are paying their own flying, and are doing it in one hit , not spreading it out over several years, allowing to get into the flying ( career ) a bit quicker.
Having a second or 3rd career also allows a safety margin to fall back on incase something goes wrong ... like the aviation industrys ass falling out of it ...as it has done in the past or just difficult to get a job , at least I can earn the money to pay for my own flight time if I need to.
To anyone that decides thats what they want , Age makes no difference.
