Well I witnessed a diver who had been certified nearly 20 years earlier. They were planning on going somewhere to dive and wanted to get a refresher course before they did. Probably a good thing they did because despite the fact that she had dove avidly years earlier she apparently over the 20 year period of non diving lost her ability to do simple skills like mask flooding. She tried and tried and tried but it just would not work.
What you have to remember is over time lots of things change that seem minor as we witness it.
One really way to notice this is to watch movies like Jaws and the scene where divers were going in and you will notice a variety of modern no nos. Regs with no octos, Horse Collar style floatation devices and the list goes on. Just imagine what all has changed since you got certified
