you seem to be obsessed with this age thing...

I don't see what difference it could possibly make!!!!

I have friends that are seniors at our field that have a great wealth of information and are up on all the latest planes/equipment they fly wild 3d and are very willing to take risks with there planes.
There are also seniors there that live in the past and are flying planes with 20 year old technology....they do very little or no reading on new technologies and are not interested in discussing anything new. they fly the same way they did 20 years ago and haven't a clue how to fly 3d nor do they have any ambition to try.

there are also much younger guys at our field that seem to be very knowledgeable with only a few years experience, they fly as if they have been flying 3d for 10 years ...but...on the other hand ....there are young people flying like they were 80 years old and seem to have learned almost nothing, even though they have been in the hobby for several years!!!

I am trying to remember when I was 13, if age was that big a concern.....it probably was!! Relax ...enjoy... In a few more years it won't make a difference to you at all
