My mom is 50. She's had 6 lucid dreams since June, but she doesn't do any techniques. She doesn't know any of the techniques, she RARELY does reality checks, she does not keep a dream journal (I keep one for her because she tells me, then forgets hers), does not come onto this website, etc. She loves sleeping and dreaming though and has at least ~3 dreams recalled per night.

I like to think that she has lucids just because I'm always babbling about them to her, she only had a couple as a child until April, when I really got into LDing and wouldn't stop talking about it

So imagine, if you put in the effort, YES you can have lucids and you'll probably have a LOT! Just like everyone else

On another note, I really like how many of the members here think that 40 is old... Wow. Too much LDing, you guys have a very strange sense of reality!
