As others have said, full-disk encryption mitigates this risk. I started
using that after I once left my laptop in a Metro in Rome, back in the
'90ies.
This will protect your data (provided your passphrase is strong enough) in
the case someone gets hold of your harddisk.
It won't protect you from
- someone taking over your running system (think Javascript + a
vulnerability in your browser
- someone planting something in the part of your boot process
*before* you enter the passphrase (the so-called "evil chambermaid
attack[1])

[1] Yes, it's a sexist moniker. I don't like it either. Search engines,
alas, only help you if you use it. Creative alternatives welcome!
