indigo I always had smallish boobs but since I've got older (and yes, put on weight) they've become decidedly more "middle-aged and musky". So much so that I have to wear a "good bra" now instead of the teenage design ones I used to get able to get away with. I don't really like it, but it doesn't cause me any problems.
On the other hand, an acquaintance had breast enhancement options at 63! She was completely flat chested all her life and said she wanted to have boobs.
If you are experiencing pain, you should see a doc. There was a previous thread about this subject, and one of the gransnetters was having a reduction. I'll see whether I can find it.
