Probably about 30-35 times for me. Most of them were when i first started playing. 13 of them were on my first day. After that, about 10 more when i was on peaceful (I didn't know what peaceful mode did, nor did i know about shift). Now, i hardly ever die to monsters, lava, or players. Most of the recent ones were suicides.
