Which Historical Figure Am I?

You take Robert Downey Jr.’s version (And ONLY Robert Downey Jr.’s version) of Sherlock Holmes,
Bring him yonder here and up-to-date, ⏪⬆️
Subtract his Watson ⏬,
Housekeeper ⏬⏬, and mysterious Source of financial support ⏬⏬⏬,
Add back about 10 years in age, ⏬⏬⏬
Remove his active cases and Other Endeavors requiring the use of his mega-quick wits, 💤💤💤💤
[Thereby removing his Physical and Mental Ability to Exercise through Physical and Mental Activity: the very DEFINITION of Insanity-Provoking] 🌰🥜‼️

And the Historical Figure who’s been left behind is ME. 😶‍🌫️
