   1.                                                   For each of the common
stock shares being registered for resale, disclose the price that the
                                                        selling securityholders
paid for such shares.
   2.                                                   We note the significant
number of redemptions of your common stock in connection with
                                                        your business
combination and that the shares being registered for resale will constitute a
                                                        considerable percentage
of your public float. We also note that many of the shares being
                                                        registered for resale
were purchased by the selling securityholders for prices considerably
                                                        below the current
market price of the common stock. Highlight the significant negative
                                                        impact sales of shares
on this registration statement could have on the public trading price
                                                        of the common stock.

Prospectus Summary
Overview, page 6

3.       In light of the significant number of redemptions and LifeForce
Capital not funding the
         $16.2 million pursuant to a certain subscription agreement entered
into concurrently with
         the execution of the Business Combination Agreement in December 2021,
expand your
         discussion of capital resources to address any changes in the company
 s liquidity position
         since the business combination. If the company is likely to have to
seek additional capital,
         discuss the effect of this offering on the company   s ability to
raise additional capital.
4.       Please expand your discussion here to reflect the fact that this
offering involves the
         potential sale of a substantial portion of shares for resale and
discuss how such sales could
         impact the market price of the company   s common stock.
Risk Factors, page 11

5.       Include an additional risk factor highlighting the negative pressure
potential sales of
         shares pursuant to this registration statement could have on the
public trading price of the
         common stock. To illustrate this risk, disclose the purchase price of
the securities being
         registered for resale and the percentage that these shares currently
represent of the total
         number of shares outstanding. Also disclose that even though the
current trading price is
         significantly below the SPAC IPO price, the private investors have an
incentive to sell
         because they will still profit on sales because of the lower price
that they purchased their
         shares than the public investors.
General

6.       Revise your prospectus to disclose the price that each selling
securityholder paid for the
         shares being registered for resale. Highlight any differences in the
current trading price,
         the prices that the sponsor, private placement investors, PIPE
investors, and any other
         selling securityholders acquired their shares, and the price that the
public securityholders
         acquired their shares. Disclose that while the sponsor, private
placement investors, PIPE
         investors, and any other selling securityholders may experience a
positive rate of return
         based on the current trading price, the public securityholders may not
experience a similar
         rate of return on the securities they purchased due to differences in
the purchase prices and
         the current trading price. Please also disclose the potential profit
the selling
         securityholders will earn based on the current trading price. Lastly,
please include
         appropriate risk factor disclosure.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
