Tethered headsets are physically connected to the laptop or computer. It is a much more complex system that gives an ultimate VR experience. The VR headset for iPhones works pretty well with iPhone, giving the user an awesome virtual reality experience.
DHA (docosahexaenoic acid) is an omega-3 fatty acid often recommended to women during pregnancy. Thought to protect against a number of pregnancy-related complications, DHA is also said to promote the health of the developing child.
Salmon, canned light tuna, and products with added DHA such as eggs and milk are all good options, as are anchovies, herring, sardines, walnuts, and walnut oil. If you'd rather take a DHA supplement, go for one derived from algae rather than fish oil â it'll be gentler on your stomach. (Then you'll be getting your DHA just as the fish do; their source is marine algae.) Eating Fish Safely. Fish is a fantastic source of DHA, but pregnant and breastfeeding women need to exercise caution. You want to eat enough oily, fatty fish to reap the DHA benefits but not enough to add too much dangerous mercury to your diet (and your baby's).
