Does apply for a "retirement Visa " (e.i.  50 years old) year in which you had  born , or just on day of yours birthday? ... (in my case  have birthday 9.Novembra, 1967)  
 

In February last year 2015, I came to Thailand with a Visa Medical Treatment (MT) .. non-immigrant "MT" multiple. The Visa MT I get in Slovenia. I am invalid-pensioner.
I had every 3 months to go to the Cambodia border that they put a stamp and  get the Visa in the country where I am. I do that for 15 months before the Visa MT had expired.
Then I went to Malaysia after a new Thai Visa for 3 months ... 2 month + 1 month which  can stamp on Jomtien immigration office. 
I been in Malaysia 3 time, and 3 time can do that. (I did not know that you could make an application for 1 years, non-immigrat multiple in Malaysia or Laos, or Cambodia). 
Well there in Malaysia Thai Consulate gave me an ultimatum that do new  Visa or in Slovenia EU or to qualify for a retirement Visa in Thailand. 
I have Thai Visa to 1. Februar 2017.

You will need to wait until your birthday next year to apply for a visa for being 50 or over.

You need to go to a different location than Penang to get more tourist visas. You could get 3 more in Vientiane Laos.

Jupi!! 3 more I only need to end of winter time than back to EU and make new Thai Visa.

And very useful information to wait to 50 age birthday, and  go to somewhere else overboard.
