Is there some age limit for normal guys who wanna learn Perl?

I used to have to deal with a development group manager who firmly believed that "you should stop trying to learn anything new at age 40."

I had two words to answer him with: "Bovine Scatology!."

I've never stopped learning. It may be harder to do at times and I'm in my mid fifties. Since I turned forty the stuff I've learned to do from a standing start include (but are not limited to)

• How to make Belgian (style) Ales.
• JSP, Java Server Faces (JSF), Hibernate Programming
• Tomcat
• Puppet
• Nagios
• Arduino
• Italian Cooking
• How to smoke meats (finding the right end to light helps)
• Sausage making
• How to train dogs
• How to rehabilitate aggressive dogs
• Dog Agility handling
• Rally handling

Point is the time to stop learning stuff is when you get that underground and really small apartment with no exits.

I don't plan on moving into that apartment yet, so I don't plan on stopping learning. Even stuff that I've already learned there is still a learning process as you hone your knowledge to a finer point and you get better at it.

As for forgetting syntax... memory is the second thing that fails as you get older...
