i dont get your question, except that your older so u dont understand how to..?? if thats the question there are tons of places where you can make a free email address & it never cots money to send an email so start here yahoo.com u can make a free email on here, or on hotmail.com & im sure theres lots of other sites w/ free email.
There's absolutely nothing wrong with your age, if you're "reasonable". Say if you want to email someone 60+ years old, I don't see any problem with it.
