Just because someone is lucky enough to never have noticed effect from exposure doesn't mean you shouldn't take precautions. The effects of neurotoxins aren't always apparent and accumulate over long periods. Things like dementia/Alzheimer's are known to have links to metal and toxic vapor exposure. Let's not rule out genetic pre-disposition either. So why take a risk? Make sure your work area is well ventilated regardless of what product you use.
I use a cheap bathroom fan with some 5$ coil ducting to pull the fumes out to a window and I must say my soldering work is much more pleasant than it used to be!

> NoClean -- as it say, don't try to clean it! Without a lot of work you'll just end up with sticky gunk everywhere (even if you use, for example, Warton's specially formulated stuff for their own solder, then try further with IPA [the cleaning alcohol, not the beer!]). There is rarely any need to worry about cleaning in a non-production environment.
> Frankly, I wish people (US in particular) would finally get on board with lead-free - it is not f'ing scary.. It is annoying to get kits that are non-RoHS in this day & age. Many PCB houses are now making RoHS boards as standard and most components are RoHS as standard too (otherwise they'd miss out on a chunk of the market). Sure, a small guy can easily fly below the official RoHS radar, but that's not really the point.
