What instrument could I self learn?

[numtumfutunch]

Quite simply whats the 'best' instrument for a non musical middle aged bloke to try and get a grip of please?

The background is that I have decided I need a challenge to stop my brain cells decaying.

Although I love listening to music I have absolutely no musical talent and never even picked up a recorder at school.
I cant read music and struggle to know if one notes higher or lower than another.

So I expect this to be pretty tricky, although having said that if Status Quo say learning 2 chords will play most of their songs Im in with an outside chance

Ive no affiliation to any particular instrument and dont have neighbours near enough to worry about
I am under no illusion it wont be tough and Im prepared to put the graft and hours in

Due to work patterns I'll struggle to fit in regular lessons and so wonder if books and Youtube are viable?

Choice of instrument entirely negotiable - but its hard to look further than guitar
Id obvs love to be able to nail the intro to Layla

Anyone else done similar from scratch? Any tips?

All comments welcome

Cheers
