22 can be easier than 42 if there's precipitation involved. When it's cold and raining you have to have good gear.
Get gear that breathes. In an emergency I once rode with kitchen rubber gloves under my gloves and was warm. If your gloves don't evaporate sweat well, though, your fingers will quickly go numb.
I keep some goggles handy because when a freezing wind hits your face, you're going to be blinded with tears.
Carry some extra clothes in the event of a breakdown.
Aluminum is not corrosion proof. Keep your bike clean of road salt regardless of what it's made of. Or keep it outside so the cold slows chemical reactions and keeps ice from melting and refreezing inside various mechanisms.
Maybe get a cheap winter wheelset. Road salt and slush do a very good job of keeping grit stuck to your rims and brakes.
Last, don't forget that strenuous exercise may warm your core but does not protect against frostbite because stress pulls blood away from your extremities.
In spite of the above, I still do winter riding for fun. It's not that big a deal if you prepare.
