What are the current requirements for a one-year extension of stay in Thailand based on age?

--Information Only- So, Once again I completed my one year extension of stay based on being over 50 (Commonly, and incorrectly referred to as retirement visa) at Samut Prakan immigration today. I used the 800K banked money method in a Time deposit account and obtained the bank letter and updated the book yesterday afternoon. Since last year's visit the TM.7, 'Acknowledgement of penalties for overstay' and 'Acknowledgement of terms and conditions for permit of temporary stay' are all exactly the same but in a slightly different font, so I had to rewrite them. They no longer require the 'Foreign national information form', but they do require a photocopy of your TM.30 (which is new). I used my Yellow book for address purposes, but curiously they asked for my Wife's Tabien Baan (which she hadnt brought, but they were happy with a photocopy of her ID card). Copies of passport info page, last visa stamp, Last entry stamp, TM.6 (both sides) and last extension of stay stamp rounded out the paperwork. In and out in a little over 90 minutes which I was quite happy with. Be advised the photocopy booth has moved outside and has long queues.
