    as one ages one's eyes become less light sensitive due to cataracts (or something like it) really bright lights are a Godsend, illuminating the dark spaces as well as blinding the bad guys. A tactical light may be the best investment you can make

    The only problem with this is it only works when there is a temperature differential. Thus your hand is warmer or cooler than the ambient air (yes, it does work both ways).
