A lot of grandpas here. Joke!
I am twenty eight years old. This just remenbered me a old joke:
Man compared to aircrafts:
Man up to 20 years:
Paper Airplane
Only fast flights, short range and duration.
20 to 30:
Fighter Military Plane
Always available, seven days a week.
Attacks any target. Multi-role, able to perform various tasks, even when separated by short intervals of time ...
From 30 to 40:
Commercial aircraft on regional routes
Maintain a regular schedule.
Well known destinations and routine.
The flights do not always come on time, which requires changes and adaptations that irritate customers.
40 to 50:
Commercial aircraft on international flights
Opera-time luxury.
High level destinations.
Long flights, with a few surprises.
The customer arrives with great expectations, in the end, get tired, but satisfied.
50 to 60:
Cargo Aircraft
Intense preparation and hard work before takeoff.
Once airborne, move slowly and show greater discomfort during travel.
The clientele consists mainly of several bags and stash.
From 60 to 70:
Hang Gliding
Requires excellent external conditions to take flight.
Give a big job to take off and then avoid abrupt maneuvers not to fall soon.
After landing, dismantle and store the equipment.
From 70 to 80:
Glider
Only flies with assistance.
Extremely limited repertoire of tricks.
Once on the ground, need help to get back to the hangar.
After 80:
Aeromodel.
Only ornament.
Remenber, its just joke! Be sportmanship!
