It certainly doesn't vary widely, but there are small variations from year to year.
To find steady state heart rate, subtract your age from 180, that's steady state. For example, 25 year old's steady state would be 155. This isn't 100% accurate, the best way would be to use lactate samples; however, this is the most practical.

We can certainly reproduce and make fusion happen but not at the rate required to produce enough energy to make the process viable for our energy needs, it is estimated it will take around 20-30 years to refine our fusion method to a point where we can output a large amount of energy from it.
In transient heat transfer, the rate of heat transfer is changing with time. By definition, in steady-state heat transfer, the rate of heat transfer does NOT change with time. In the real world, heat transfer starts out as transient and then approaches steady-state with time until the difference between the actual and the ideal becomes negligible or until thermal equilibrium is approached.

This actually depends on the annuity. A "fixed" annuity always gets you the same rate, while the rate of a "variable" annuity is indexed to some other rate, usually the federal prime rate. Rates are variable over the long term. It is possible to lock a steady rate in but it costs more to do so.

Fusion reactions decrease the overall number of particles in the core, causing the core to shrink, converting gravitational potential energy into thermal energy, and increasing the rate of fusion.
