Do ever feel like everyone's watching you? for example say you're going to the shop's or out and about.

Definitely not.

I dress in a way that blends in, doesn't attract attention - and prefer it that way.
Plus I'm way past 50, and people tend to avert their eyes and pretend not to see the elderly,
unless you're right in front of them as a customer or client, (except for friends, pets and family).
