Yeah, maybe only old people voluntarily complete weekly surveys

Given a random sample is unlikely, it might be of more interest to look at the demographics of those who post messages in response to a survey.
Perhaps, for that cohort, considering years on CP, as well as (if available) biological age, could be interesting.
Part of the "elephant in the room" may be that a large group of people never see the surveys because they don't visit the home page, or, see them, but, just never "do" surveys.

I seem to remember your birthdate was an optional part of your profile at one time. It seems to have been removed, unfortunately (for this circumstance). We could have curried the member list for active members and charted their ages.

now that birthdays are verboten in the net-arena, what happens if OriginalGriff's brain stops keeping track ?
I use moon-cycles now, because total-months/13+(calculatephasefactor(dob, now)) means one more b-day is a smaller slice off the cut loaf.

I'm old and retired but I love programming enough that I regularly spend 3 or 4 hours a day coding and understand what I am doing so much more than I ever did before. I'm not available for hire though because no way will I work more than those 3 or 4 hours.

That should not be a big problem. You are probably going to be more productive than some working 8-10 hours

As one of the seniors I wanted to respond to this... but seems
I don't remember now exactly what I wanted to say other
than I *do* purchase things and think "the last one I'll
ever need to buy - barring misadventure". One must always
allow for misadventure.

As to first. Bought a car in July. As little as I drive plus my advanced age, pretty good chance this will be the last car I ever buy.
Same with washer & dryer I replaced the last couple years.

I have T-shirts that are older than many of the engineers that I work with these days. It amazes them that I instantly have solutions to almost all of their programming problems. I'm getting bored with saying "been there, done that."

I've done a repartition and format, but I understand that I should shred it as well. When I tried the command "shred", it said it didn't understand the command. 
|
|
|
|
|
I have never heard of the term "shred" in regards to the partitioning process.
This is a first.
|
|
|
|
|
AFAIK, gparted does not have a shred option. There is a shred command available from the command line and you should be able to do
sudo shred -v /dev/sdX . That will erase the whole drive. I've not tried it but I expect that shed -v /dev/sdXP would erase partition P. Check the docs on that. Note that this will erase the formatting, so you'll have to recreate the file system(s) for any partitions you shred.
If you don't have shred installed, or can't install it for some reason, then you can use dd
dd if=/dev/zero of=/dev/sdX bs=4M will overwrite the harddrive with all zeros. You might also use if=/dev/urandom, to write random-ish data over the drive before formatting.
Keep Calm and Carry On

The system will be given to charity, so I don't care what condition the hard drive is in.

I did:
if=/dev/urandom
and the console window started printing random characters.

If you formatted the drive - it is clean. What shred refers to is to deletion. Deleted files and folders are not actually removed. Deletion does not destroy the data itself. It only flips the flag in a file table that this particular data sector is no longer needed and can be overwritten should the drive volume get low. If the drive volume never gets low then the data which is not overwritten remains there perpetually and can be recovered. Byte 0 in FAT table: value 0x00 = unallocated and 0xE5 = deleted
