Voltage causes current to flow. Current that passes through a body depends on the body Resistance and the Voltage applied across. Different bodies have different resistances and also that varies time to time with the body conditions. A wet body will conduct more on surface where as a fatty body conducts more through muscles. In a nut shell, current flows more through the low resistive parts.
Flow of current spends energy and is converted normally in to heat and that damages the body components which is called Electrocution. This mostly causes irreversible damages to the body components, which may or may not cause death depends on which part of the body is affected. Shock is a phinominon with nerves that are affected. They are the carriers of senses and very sensible too. When they are stimulated with high currents, they act crazy and impulsive which affects the operations of the entire body systems. Also the pyschological fear that throws a person away which leads cardiac arrests that mainly kills people than electrocution.
Regarding safe Voltages, upto 48 Volts are safe to be handled with hand. Any thing above will have an impact. Normal human will have a better feel of the shock (electrocution) from 110 Volts across him. Some people even experience a mild shock at 48 Volts also. Let me once again reitterate. It is the current that flows a body that causes the damage and not the voltage. But the Voltage in relation to the body resistance causes the flow of current. Any thing above 0.1 Amps causes damage to tissues.

Actually, different people have different sensitivity. Very sensitive people begin to feel the potential at about 24 Volts, while the threshold of tolerability is roughly 48Volts, which is not exactly where one gets hurt. 60Volts and above it becomes harmful. Higher the voltage, stronger the effect. At mains voltage (230V AC) the current may be around 0.0007A, yet it could kill in 2 to 5 minutes. At 440V it could kill within 2 to 5 seconds. And of course, our tongue can sense current at only 1.5V, due to electrolytic effect. (Typical body resistance between two palms is around 400 to 500k--but lower in monsoon, during perspiration etc.)

First of all, electric current is not measured in volts, it's measured in amperes. Voltage or potential difference is measured in volts

Current is measured in amperes while electrical potential is measured in volts. I think current is more important than voltage as far as electrocution goes.

HARMFUL: 24 volts on wet medium and 50 volts on dry medium but it depends on skin resistance and tiredness of nervous sistem (ex.: in the evening the resistance is lower).

24 volts and over can be lethal if goes through the heart for few seconds, we are all individuals and it can vary from person to person.
Your tongue can fee 1.5 volts as trickle, try any small battery with 1 wire, or 2 wire and a battery.
