Things you do that you wouldn't encourage others to do

[WomenHour]

I would say drink so much fizzy pop

Eat too many biscuits a day!

A lot! I go solo hiking and bush camping, swimming alone in lakes, rivers and the ocean, drive cross country on my own, that sort of thing.
Nothing wrong with the activities in themselves, but it is so much better (and safer ) if you have a partner.

Get fat! I wished I had managed my weight better when it started creeping on, it is so hard to lose a lot.

Step off the housing ladder

Spend too much time on Mumsnet

Eat sweet snacks

Overthink

Leave a job without having another one to go to

Eat all the ice-cream.left after a dinner party

Not now but due to work walk through the city center at stupid oclock at night / early hrs of the morning.
